Principles and Techniques of Biochemistry and Molecular Biology
by Keith Wilson and John Walker

The Human Genome Project in particular has been the stimulus for major developments in our understanding of many human diseases especially cancer and for the identification of strategies that might be used to combat these diseases. The discipline of molecular biology overlaps with that of biochemistry and in many respects the aims of the two disciplines complement each other. Molecular biology is focussed on the molecular understanding of the processes of replication, transcription and translation of genetic material whereas biochemistry exploits the techniques and findings of molecular biology to advance our understanding of such cellular processes as cell signalling and apoptosis. The result is that the two disciplines now have the opportunity to address issues such as: • the structure and function of the total protein component of the cell (proteomics) and of all the small molecules in the cell (metabolomics); • the mechanisms involved in the control of gene expression;
