Origin of Genetics and Molecular biology



Genetics is the study of heredity, the process by which characters are passed from parents to their offsprings, so that all offsprings resemble their parents.

The first Geneticists had mainly worked how characters are transmitted from parents to offsprings and how genes act together to control variable traits such as length, height, coat colour, flower colour etc. They developed the central; concept of Genetics. According to this concept heredity is controlled by large number of genes, that are located on the chromosomes. These are called ‘hereditary vehicles’. During 1930s beginning was made to apply biochemical and biophysical methods for the study of chemical nature of gene. This led to a new branch of genetics-Molecular biology. This new approach led to the concept that genes are units of biological information. The geneticists and molecular biologists are working together to understand the way in which biological information is stored in genes and how this information is made available to living cell for its maintenance and division.

Because of close association and interdependence between genetics and molecular biology the term Molecular genetics is now used. It is that branch of biology that is concerned with the study of all aspects of gene.
