Have an impact on the development of new or improved medicines and the treatment of disease. Biochemistry is the study of the biological systems at the molecular level and develops understanding of the molecular basis of life, and how alteration of these molecular pathways leads to disease processes. Microbiology is the study of the smallest living organisms such as viruses, bacteria, fungi, algae and protozoa. Microbes are a major cause of disease but they can also be useful in industrial processes. You take introductory classes in biochemistry, immunology, microbiology and pharmacology in Years 1 & 2 and whichever biomolecular science degree you apply for, you can defer your final choice of degree until the end of Year 2.
