Molecular biology is defined as ‘‘the study of the structure and function of large molecules associated with living organisms, in particular proteins and the nucleic acids DNA and RNA’’ (Oxford Dictionary of Biology, 4th ed., 2000), while cellular biology is the study of cells, ‘‘the structural and functional unit of most living organisms’’ (Oxford Dictionary of Biology, 4th ed., 2000). Molecular biology is among the most rapidly growing fields within biology with recent success stories such as the sequencing of the entire human genome (reported in Science and Nature).
