Biological Sciences

As we go through the motions of our everyday lives, we take for granted the complexities of our own body and near-perfect synchrony between the different components that make us human. Often it takes sickness and disease to remind us of how remarkable our own body is.

The human body, the myriad units that make it a functional whole and agents of infection like bacteria and viruses are under investigation at the Division of Biological Sciences. To understand the research we need to start with the basic unit of all life — the cell. The cell is a highly organised bag of carbohydrates, proteins, fats and other molecules that co-exist and communicate with each other with apparent ease. A cell is never idle. The information necessary for its function is contained within the nucleus, in its genes. Genes are made of DNA (deoxyribonucleic acid), long molecules made up of repeating units which are passed on from one generation to the next.
