Molecular biology tries to explain the interactions between the various systems of acell. It studies the relationship ofDNA,RNA andhow proteins are made, and how these interactions are regulated.
Schematic relationship between biochemistry, genetics and molecular biology
Researchers in molecular biology use specific techniques that are typical for molecular biology, but they combine these with techniques and ideas fromgenetics andbiochemistry. This diagram shows one possible view of the relationship between the fields:
Cytology, which includes the appearance of cells and cell structures,microscopy, and the use ofstains and tags to help distinguishorganelles and processes.
