One of my friend is studying Molecular biology in lahore and Molecular Biology according to her is as follows:
The field of molecular biology studies macro molecules and the macro molecular mechanisms found in living things, such as the molecular nature of the gene and its mechanisms of gene replication, mutation, and expression.
The field of molecular biology arose from the convergence of work by geneticists, physicists, and structural chemists on a common problem: the structure and function of the gene.
In the early twentieth century, although the nascent field of genetics was guided by Mendel's law of segregation,the actual mechanisms of gene reproduction, mutation and expression remained unknown. aik
The techniques of molecular biology enabled numerous other fields to go molecular. The study of cells was transformed from descriptive cytology into molecular cell biology. Molecular evolution developed as a phylogenetic method for the comparison of DNA sequences and whole genomes.
The term Molecular Biology was most probably invented by Warren Weaver in late 1930.
In plain words, its the branch of biology that studies life at Molecular level which is mainly concerned with the systems of cell, including DNA,RNA,proteins and their interactions.
