You examine the origins of life, cell structure and function, energy transductions, synthesis of molecules, and the eukaryotic cell cycle.
Microbes are essential for life, playing a vital role in connecting the health of humans, animals, and ecosystems. They aid in digestion, provide essential vitamins, and contribute significantly to our overall health and well-being. Marine microbes, for instance, produce approximately one-third of the oxygen we breathe. Additionally, microbes are indispensable for achieving the United Nations' Sustainable Development Goals, as they clean up pollutants and synthesize valuable products like antibiotics. However, not all microbes are beneficial - some cause devastating diseases. Despite significant advances in treatment and prevention, the incidence of infectious diseases continues to rise. In this module, you will explore the vast diversity and evolution of mostly beneficial microbes, alongside the pathogenicity of harmful ones. You will investigate how different viruses and bacteria invade, interact with, and replicate within their hosts. Through two practical sessions in our state-of-the-art teaching laboratory, you will study a food poisoning outbreak and will gain hands-on experience in growing, observing, purifying, counting, and even killing microbes. These sessions will equip you with highly sought-after skills, including aseptic technique, serial dilution, and data analysis.
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.

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.
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.
Many recent advances in biological research have been born from an increased understanding of the molecules involved in systems and processes. But what do things look like beyond molecular level?<br><br>Study how molecules are formed from individual atoms, and how the properties of these constituent atoms influence molecular structure and reactivity. Examine the fundamental concepts of chemical bonding, electronegativity, acidity, basicity, hydrogen bonding and review the common organic functional groups and different types of isomerism.
You will develop your transferable skills in scientific writing (including referencing and avoiding plagiarism), teamwork and communication through oral presentations, study and research skills (including essay writing, lecture note taking, use of library and databases). Teaching and learning will be through a mixture of lectures, classes, and tutorials. The emphasis will be on small group, tutorial-style teaching and interaction with other students on this module, with assessments tailored to your degree subject area.
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 immunopathology, 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.
Consider the structural diversity, function and method of genetic transfer among various deadly infectious agents, assessing their role in the natural world and infectious disease. You will evaluate different methods of diagnosis, review methods of hospital-acquired infection control and investigate the different pathways of transmission. You also address treatment options, reviewing the efficacy, side-effects and toxicity of drugs as well as considering the impact of disease upon society.
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.
This module aims to prepare you for carrying out an individual scientific investigation on a topic relating to your degree. Develop skills to identify a suitable question and then design an experimental approach to obtain data addressing this question. The assessment focuses on your analysis and presentation of these data in a suitable scientific paper format report, on the research, understanding and critical writing about the scientific literature relating to your project. Your oral project presentation skills and response to questions, the planning and management of your project work, your progress reflection and your employability skills will also be evaluated.
This module has been designed to enable students to integrate their subject knowledge with an understanding of sustainable development, acquiring the skills and competencies essential for addressing the urgent sustainability challenges of the 21st century.
Viruses have a major impact on humanity. They cause a number of acute human and animal diseases, which can be serious of even life-threatening but can also cause long-term complications such as paralysis. Viruses can also lead to certain types of cancers and may even cause some forms of diabetes and heart disease. Plant viruses cause considerable economic losses and are a threat for sustainable agriculture. Research over the past 20 years has transformed our understanding of viruses and has provided a number of vaccines and anti-virus therapies and prophylactics. This module will introduce you to the diversity, unique nature and importance of viruses then will show you, using a number of detailed specific examples, how molecular biology approaches are used in their study and in diverse applications. The module will highlight molecular features of disease and current approaches to control viral infections.
Microbial Biotechnology for Sustainable Development
(15 CREDITS)
Microbial biotechnology is a fast-moving field that is vital for sustainable development, economic growth and employment. In this module you will learn first-hand about the application of microbes by visiting several organisations involved in environmental, plant and medical biotechnology, including large biotechnology companies and smaller enterprises.
These visits, which will include tours and talks by experts, will bring microbial biotechnology to life. They will be supported by lectures explaining how we: turn waste into fuel, recover valuable resources, use innovative molecular techniques to detect pathogens, apply microbes to help feed the growing human population, develop new medicines and enzymes using microbial diversity and synthetic biology, and how processes can be scaled up using bioreactors. This exposure to microbial biotechnology in practice will help you to recognise the breadth and types of future employment opportunities.
