Molecular biology is the branch of biology in which the biological reactions that take place within and between cells are understood at the level of molecules . In this, the effect of different types of molecules on cells, the formation and changes of molecules in cells and all the processes and systems related to molecules in cells are studied. Microbiology treats molecules as the basis of biological interactions between all systems of cells and studies how these interactions are controlled. This specifically includes DNA , RNA , proteins and their biosynthesis .The molecular basis of biological activity between biomolecules in different systems of the cell is concerned, including the coordination between, and the regulation of, interactions related to these .
History
While molecular biology was established in the 1930s, the term was coined by Warren Weaver in 1938. Weaver was the director of natural sciences for the Rockefeller Foundation at the time and believed that biology was about to undergo a period of significant change given recent advances. Fields such as X-ray crystallography . Clinical research and medicine originating from molecular biologyThe treatments fall partly under gene therapy. The use of molecular biology or molecular cell biology approaches in medicine is now called molecular medicine. Molecular biology also plays an important role in understanding the construction, functions and regulations of the different parts of cells, which can be used to efficiently target new drugs, diagnose disease, and understand the physiology of the cell .
