Molecular biology

[tamim_saif]

Molecular biology is the study of biology at a molecular level.
The 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 interrelationship of DNA, RNA and protein synthesis and learning how these interactions are regulated. Researchers in molecular biology use specific techniques native to molecular biology, but increasingly combine these with techniques and ideas from genetics and biochemistry.
