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 interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Cryogenic electron microscopy helps visualize 3D structure of complex responsible for gene regulation

A research team has looked inside a human cell to visualize a multi-subunit machine that is responsible for controlling the expression of genes.
