Science of molecular biology

Molecular biology chiefly studies the interactions between the various systems in the cells, or studying the formation, structure and function of the macromolecules essential for life, such as nucleic acids (DNA and RNA) and proteins, and particularly their role in the replication of cells and transmission of genetic information. Molecular biologists study the molecular basis of living organisms. They study how genetic information can be encoded in the molecules of deoxyribonucleic acid (DNA) and how this information can be used for the synthesis of all other molecules that make up living…
