mo·lec·u·lar bi·ol·o·gy

study of phenomena in terms of biology molecular (or chemical) interactions; traditionally, the focus of molecular biology is more specific than biochemistry in that it has an emphasis on chemical interactions involved in the replication of DNA, its "transcription" into RNA, and its "translation" into or expression in protein, that is, in the chemical reactions connecting genotype and phenotype.

molecular biology

A major discipline that marked its birth with Watson and Crick's seminal report, 'General Implications of the Structure of Deoxyribonucleic Acid', which elucidated the double helical nature of DNA; MB seeks to understand the mechanisms controlling gene expression, in physiologic and disease states, and provide the tools necessary for treating genetic diseases.

molecular biology

The study of cellular phenomena, and especially genetics, at a molecular or chemical level. As knowledge has progressed the term has become more and more synonymous with ‘biology’, for, today, biology aims at nothing less than a full understanding of the functioning of living things in terms of the nature and interactions of their molecules.
