Molecular Biology

Molecular biology is a specialized branch of Biology and Biochemistry, which are specifically concerned with the study of various biological activities at the molecular level.

Molecular biology includes different biomolecules like the AminoAcids, Nucleic acids (DNA and RNA) proteins, carbohydrates, and lipids, along with their compositions, interactions, structure, and functions in the life processes.

The term “Molecular Biology” was coined by an American scientist, Warren Weaver in the year 1938. As per the records, the discovery of molecular biology began in the early 1940s and its fundamental development took place in the year 1953, during the invention of the double-helical structure of the DNA molecule by the two molecular biologists named James Watson and Francis Crick.

Important Topics in Molecular Biology

What is Molecular Biology?

Molecular biology is the study of living things at their molecular level, which controls and make them up. It is also used to study and understand:

  • The Molecular pathways within the cells
  • How living things interact with the populations?
  • How Proteins and nucleic acids interact with the biomolecules?

The study of Molecular biology will establish a strong foundation on the fundamental importance of the 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 is also closely related to other sub-disciplines like biochemistry, cell biology, genetics, and genomics.
