Molecular biology

Noun 1. (biology, biochemistry) The branch of biology that studies the macromolecules of life, such as proteins, lipoproteins and nucleic acids. ( 2. (Genetics) The branch of biology that studies the manipulation of genetic sequence of DNA. ( 3. (Genetics) The technology of gene manipulation. ( 4. The branch of biology that deals with the molecular basis of biological activity. This field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between the different types of DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated. ( 5. The study of the biochemistry of cells, it is closely linked to cell biology, in particular the biochemistry of DNA and cogeners. The branch of biology that studies the structure and activity of macromolecules essential to life (and especially with their genetic role).The study of biology at the molecular level, such as the chemical properties of DNA. ( 6. A discipline concerned with studying Biological Phenomena in terms of the chemical and physical interactions of molecules....
