Molecular Biology can simply be defined as the sphere of biology which analyses the compound, structure and correlations of the cellular molecules like protein and nucleic acids that helps in accomplishing the biological processes significant for cell functioning. This particular field of science focuses on the analysis and study of the structure or processes of certain chemicals and biological phenomena which comprises the fundamental cells and units of life.

The study of molecular biology has been gaining popularity since the year 1940. Molecular biology can be considered as the grown out of numerous fields like genetics and biochemistry etc. We all are well aware of the fact that macromolecules are crucial for the processes of life. The main concern of this discipline is the thorough study and analysis of nucleic acids and proteins. The study related to molecular biology aspires to apprehend the three- dimensional pattern of the macromolecules which is possible through the usage of techniques like electron microscopy and X-ray etc. The chief motive of this particular analysis and study is to comprehend the fundamentals of genetic processes, sequence, mapping the locus of genes and modification of certain genes etc.
