The type of biology concerned with the study of structures and processes at the cellular level and particularly of intracellular responses such as the role of a protein, an enzyme, and other chemicals in a metabolic pathway; how nucleic acid stores information affecting cellular structure and function; and how metabolites in one cell may affect the function of other cells.
An aspect of biology that seeks to understand, explain, or rationalize biologic phenomena in terms of molecular (or chemical) interactions.
A term coined by Vannevar Bush during the 1940s that eventually came to mean the study and manipulation of molecules that constitute, or interact with, cells. Molecular biology as a distinct scientific discipline originated largely as a result of a decision to provide “support for the application of new physical and chemical techniques to biology” during the 1930s by Warren Weaver, director of the biology (funding) program at America’s Rockefeller Foundation (a philanthropic organization).
The study of the molecules of living matter.
The study of the molecules that are associated with living organisms, especially proteins and nucleic acids.
The study of DNA, proteins, and other molecular constituents of cells.
