Molecular biology

From Wikipedia, the free encyclopedia

Molecular biology  is the branch of biology that deals with the molecular basis of biological activity.

 This field overlaps with other areas of biology and chemistry, particularlygenetics and biochemistry. Molecular biology

 chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interact

ions between the different types of DNA, RNA and protein biosynthesis as well as learning how these interactions are 

regulated.

Writing in Nature in 1961, William Astbury described molecular biology as

"...not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with

the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan.

It is concerned particularly with the forms of biological molecules and [...] is predominantly three-dimensional

and structural—which does not mean, however, that it is merely a refinement of morphology.

It must at the same time inquire into genesis and function."^[1]
