About the course
As a biologist you explore the true science of life. There is an ongoing need for the application of biological research, and some of the greatest scientific accomplishments of the future are likely to result from this. We’re investigating bioengineering projects, the development of renewable resource, and the potential for genetics and genomics to revolutionise medicine and health.
The vast and diverse world of living organisms offers a huge range of potential for study and work, and at Essex we give you the opportunity to explore the impact of climate change on coral reefs, the biology of sporting achievements, and cancer and stem cell biology, to the development of new artificial blood products.
You have a large degree of flexibility in order to tailor your degree to your interests, whether they be cellular or molecular biology, or field-based ecological science. You can choose from a wide range of areas, including:
- Animal behaviour and ecology
- Plant biotechnology
- Coral reef ecology
- Cancer biology
You learn modern lab techniques, take part in specialist field trips, and play your own part in adding to the ever-growing knowledge within biological sciences.
“I chose to study BSc Biological Sciences at Essex because it’s a very broad course with lots of choice for optional modules. The thing I enjoyed most was the field trip to Indonesia, as it was interesting to experience another culture and see the diversity of coral reefs in the Indo-Pacific."
Matt Wilby, BSc Biological Sciences 2015
Our BSc Biological Sciences is approved by the Royal Society of Biology.
Your education extends beyond the University campus. We support you extending your education through providing the option of an additional year at no extra cost. The four-year version of our degree allows you to spend the third year studying abroad in an English-speaking country or employed on a placement, while otherwise remaining identical to the three-year course.

Studying at Essex is about discovering yourself, so your course combines compulsory and optional modules to make sure you gain key knowledge in the discipline, while having as much freedom as possible to explore your own interests. Our research-led teaching is continually evolving to address the latest challenges and breakthroughs in the field, therefore to ensure your course is as relevant and up-to-date as possible your core module structure may be subject to change.
For many of our courses you’ll have a wide range of optional modules to choose from – those listed in this example structure are just a selection of those available. The opportunity to take optional modules will depend on the number of core modules within any year of the course. In many instances, the flexibility to take optional modules increases as you progress through the course.
Our Programme Specification gives more detail about the structure available to our current first-year students, including details of all optional modules.
The building blocks of life, plants and animals depend on the actions of individual cells. Investigate the biochemical characteristics of the small molecules and large macromolecules that allow cells to function. You examine the origins of life, cell structure and function, energy transductions, synthesis of molecules, and the eukaryotic cell cycle.
Why do we all look different? Are some illnesses hereditary? Are animals born ready-suited to their environment? From the early theories of Mendel to modern studies in molecular genetics, you explore how scientists have answered these questions over the last 150 years.
Examine how the structure and function of DNA allows genetic material to be expressed, replicated and inherited, and consider how genetic variation leads to adaptive evolution. From developing new technologies in gene cloning to the applications for modern medicine, you explore how geneticists are building on the earlier achievements in this fundamentally important field to enhance our understanding of life on earth.
Get to know the culprits of some of the world’s deadliest diseases.
Despite major advances in treatment and prevention, incidences of infectious disease continue to rise. Vast diversity, rapid evolution and the opportunistic nature of micro-organisms present a significant challenge. You examine how different viruses and bacteria invade, interact and replicate within living hosts, and explore the consequent impact on ecology, industry and disease.
A series of four practical sessions allows you to get hands-on and develop valuable skills. You learn how to purify, observe, count and kill micro-organisms in our purpose-built labs, gaining experience of aseptic techniques, serial dilution, response to antibiotics, and staining.
Living life on a knife’s edge – explore the vital role plants play in our biosphere, their diversity and intricate relationships that support our planet. Examine the value of these natural resources; examine the consequences we face when the balance is disturbed.
From studying how plants affect and are affected by their environment you learn what we can expect from a changing world. Examine how we influence the world around us. You apply this knowledge to the field, learning to collect, present, analyse and eventually interpret data.
Understanding the fundamentals of ecology and plant diversity allows you to explore possible solutions to our environmental problems.
The diversity of life on planet Earth is breath taking. We share our home with a vast number of species, a large portion of which are animals. We will discover the diversity of animal forms and functions and the role of natural selection in determining individual behaviour such as foraging, breeding and predator escape. You also investigate the idea that nothing in ecology and evolution makes sense in isolation.
Develop your skillset and boost your CV. This module prepares you for the coursework, laboratory practicals and research projects that you will encounter during undergraduate study. Get to know referencing systems and learn how to effectively communicate scientific information. Use scientific units and simple algebra and demonstrate understanding of logarithms, exponentials, geometry and elementary calculus. Learn how to design experiments, handle data and display, interpret and analyse basic statistics.
Teaching and learning will be through a mixture of lectures, classes, practicals and tutorials, with an emphasis on developing the key transferable skills needed for a career in biosciences.
Explore the building blocks of life. From the proteins that make up our genetic code to the lipids that envelope our cells, explore the structure, function and biological role of the major macromolecules.
You investigate the basic principles of protein structural bioinformatics and protein structural evolution, examine how ligand-binding equilibria may form the basis of diverse biological phenomena, learn the structure and properties of monosaccharides and polysaccharides and review the major types of lipids.
This module develops key skills in analysis and interpretation of data, biochemical methodology and calculation of biochemical parameters.
The marine realm covers 70% of the Earth's surface. It contains ice-covered seas and hydrothermal vents, muddy estuaries, deep ocean trenches and the clear blue open sea. The oceans and seas are also integral to the whole earth-ocean-atmosphere system, which controls the climate and conditions for life on Earth.
Discover the different marine environments, the organisms that inhabit them and their ecological interactions. You also investigate the physical and chemical conditions that determine the diversity of marine life and consider how human activity is influencing marine ecosystems, through overfishing, pollution, and climate change.
Develop your practical and critical thinking skills during this week-long summer module. Basic knowledge gained from molecular biology is now being applied to solve industrial scale biological problems. You will rationally design bacteria by engineering DNA and transforming your microbe in the lab before presenting your results to peers.
New approaches to environmental biology focus on examining species interactions, rather than individual taxa in isolation, requiring a sophisticated, interdisciplinary skill set, which incorporates field, lab, and high-tech remote sensing work. Our one week, residential field course in Portugal is designed to get you thinking like a researcher, and to develop your knowledge of the most recent approaches in field biology. You will acquire crucial field-work skills alongside skills in experimental design, data analysis, and oral presentation.
In this career-focused module you develop skills specific to your discipline, such as information retrieval, data-analysis and interpretation techniques, as well as a broader range of transferable skills, such as communication, team-work, numeracy and attention to detail. Learn how to best approach job applications, including CV and cover letter writing, aptitude testing and the interview process.
We all know food is the fuel of life – but how do our bodies turn the things we put on our plate into the energy we need to function? Study the processes that coordinate metabolism of proteins, lipids and carbohydrates, paying particular attention to organ specialisation, hormonal control, metabolic homeostasis and appetite and body weight. The consequences of disturbances to metabolism will also be discussed.
Examine how competition, predation, herbivory, mutualism, disease and parasitism affect the distribution, abundance and growth of populations, and how populations interact to affect the structure and dynamics of ecological communities. You apply this ecological knowledge to real-world problems, such as pest control and conservation.
Human activity is resulting in an ever-accelerating rate of extinction of biodiversity. Many species in the tropics are becoming extinct even before they have been described by science, while many more are threatened worldwide, including in the UK. Considering the need for biodiversity conservation, you work alongside some of the key employers in the sector including Essex Wildlife Trust and the Environment Agency. Topics include sustainable fisheries and agriculture, climate change, environmental law and captive breeding and re-introduction.
Our oceans cover 71% of the Earth’s surface and contain 97% of the planets water. This vast underwater world supports a huge diversity of living organisms – get to know them.
You learn how to assess biodiversity, measure species distribution and regulate populations. Systems of particular focus include biodiversity hot-spots such as coral reefs and rocky shores. You also have chance to practically apply your skills, examining the biodiversity of muddy and sandy shores, and investigating the morphological and genetic diversity in marine amphipods.
Microbes have been on the Earth for at least 3.5 billion years; they tolerate or require a huge range of physico-chemical extremes and perform a remarkable array of functions. This module will examine the diversity of microbes, and how they can be applied for the benefit of society and the environment, for example by bioremediation of contaminated land, recovery of oil and metals, production of biofuels and therapeutic compounds.
The importance of marine vertebrates to our aquatic systems cannot be underestimated, yet some of our most iconic underwater species are under serious threat. This module focuses on the taxonomy, physiology, ecology and conservation of the top predators and keystone species, including (but not limited to), whales, dolphins, sharks, rays, manatees, marine turtles and sea snakes.
Molecular biology is central to our knowledge of how biology "works" at a molecular level. This module explores the breadth of processes involved in the regulation of gene expression and the proteins that are made. You also discover the ever-expanding range of molecular biology techniques, including PCR, cloning and mutagenesis, and how these are applied to investigate and treat disease.
We are in the age of genomics and scientists have devised new technologies that can generate whole genome sequences in days which would once have taken years to achieve. Learn the high-throughput techniques of next-generation sequencing used to study genomes, the proteome and the interactome. Investigate how nucleotide sequences are analysed, applying the analytical tools used by research scientists and understand how new genes are discovered and their functions revealed. You also discover how our knowledge of gene structure is being applied in the emerging field of synthetic biology to create new organisms and modify existing ones by gene editing.
Our bodies are under attack. So how do we defend ourselves against foreign invaders? Explore the anatomical and structural components of the immune system and assess what happens in the event of immunodysfunction.
Utilising real-world case-studies (eg. AIDS), and looking at specific examples (eg. allergy and transplantation) you will review important aspects of clinical immunology and immuno-pathology, gaining an understanding of auto-immunity and immune-deficiencies. You will also consider the future of human immunology – evaluating how far vaccines can protect us against disease. Using the knowledge you have gained you will be able to identify areas of current immunology understanding that could lead to positive medical intervention.
The study of cells is at the centre of modern biology. Learn how cellular components determine cell structure and function, how cells communicate and how signaling pathways regulate cell fate. You also explore the regulation of the cell cycle and cell death and learn about changes that occur in cells that have become cancerous.
A solid understanding of cell biology opens doors to more specialist topics, such as plant biotechnology and cancer biology.
This five-day module will examine various aspects of conservation management strategies in action for different species and habitats around Essex. Working with Essex Wildlife Trust, The National Trust and The Forestry Commission, you are trained in survey methods and census techniques of local otter and water vole populations, as well as amphibian surveying and conservation. You examine issues such as water shortage strategies and coastal realignment, and consider management strategies for various habitats, such as ancient woodland.
How does modern biology affect our day-to-day lives? Consider the impact of recent advances on society. Transgenic crops, ever-increasing (and sometimes unwanted) prolongation of life, cloning of animals – to what extent can science be allowed to manipulate nature? And who has the final say?
Fill the skills gap. Bioinformatics is a rapidly growing discipline based on the need to obtain biologically-meaningful information from the huge volumes of DNA-sequence, gene expression and protein structure data. Traditionally the niche area of computational biologists, there is an increasing need to for every type of biologist to be able to handle large datasets. You learn by solving problems, working through example datasets in order to understand and learn how to utilise and interpret commonly used methods.
The study of human genetics is one of the fastest moving areas of scientific research today. Get to know some important emerging themes from the human genome sequence into the emerging fields of epigenetics and non-coding RNAs. You examine variations in genome sequence and structure in human populations, and consider the evidence for selection in human populations. Consider the evolution of the X chromosome and its regulation by the process of X-inactivation. You also investigate the significance of imprinting and epigenetics in human disease.
Today’s global society has 8 billion mouths to feed. So how can we use our knowledge of modern plant science to improve agricultural productivity? From genetically-engineered disease resistance, to using water and nutrients more efficiently, you consider the potential impact and implications of the latest thinking and technology.
Pollution is the introduction of substances that are harmful to the environment. It can be local or widespread. Using a range of examples you consider the major pollutants in atmospheric, terrestrial and aquatic environments, their sources and ecological effects, as well as potential ways of controlling them.
Anthropogenic stressors are putting more and more species at risk of extinction. How can we protect them? Zoos undoubtedly play a major part – you examine their role in species re-introductions and in-situ conservation, paying close attention to animal welfare and behaviour. You also examine the conservation of habitats, identifying how nature reserves are selected and managed, as well as taking part in site assessments to analyse coastal grazing marsh and quarry restoration.
If every individual on Earth enjoyed the lifestyle billed to be the most desirable, we would need six to eight Earths to provide for it. The human race needs to be more sustainable if we’re to survive until the end of the century. Evaluate the impacts on natural resources from unsustainable practices, explore the issues of waste management including current problems and possible solutions, evaluate how green places affect physical and mental health, and analyse the benefits of sustainable practices in food production and the pressures preventing them.
The aim of this module is to provide you with current knowledge and understanding of cancer. We will discuss general aspects of cancer biology (cancer statistics and risk factors, origins and multistage nature of cancer, metastasis and angiogenesis). The identification and isolation of oncogenes and tumour suppressors and the mechanism of action of their products will be analysed. We will explore cancer molecular biology and signalling pathways in cancer. We will discuss cell cycle and apoptosis and their role in the maintenance of normal cell populations and in the emergence of cancer. The principles of some of the current approaches in cancer therapy will be discussed.
Freshwater systems play an essential role in the ecology of many species. Explore the major types of freshwater habitats (streams, rivers, ponds, lakes) and examine how anthropogenic stressors such as water extraction, pollution and climate change place them under threat.
Fisheries provide food and employment to millions of people across the globe. Get to know the social and economic drivers of fishing and explore the subsequent impact on marine ecosystems. You gain an understanding of the scale and significance of fisheries and learn to critically analyse the methods used to assess their efficacy.
