Molecular biology is the study of living things at their molecular level, which controls and makes them up. It is also used to study and understand:
- The molecular pathways within the cells
- How do living things interact with the populations?
- How do proteins and nucleic acids interact with the biomolecules?
The study of molecular biology will establish a strong foundation on the fundamental importance of macromolecular mechanisms such as replication, transcription, translation and other cellular functions. The more commonly used molecular biology techniques include- Polymerase Chain Reaction, Electrophoresis, Restriction Digestion, Blotting, Cloning, etc.
The important topics covered in this subject are nucleic acids – DNA, RNA and protein synthesis in cells. Molecular biology is a branch of biology that is also closely related to other sub-disciplines like biochemistry, cell biology, genetics, and genomics.
