History of molecular biology

Molecular biology is now expected to the take the dominant role in the twenty first century that physics played in the twentieth. The branch of molecular biology deals with study of vital molecules of life like DNA, RNA and protein etc.

In the early 19th century, German romanticism emerged with the idea of the unity of plant and animal life.

In the middle of the 19th century, Charles Darwin (1809-82) proposed how living things diversified and in the process partially demystified the living world and the place of humans in it.

The starting point of molecular biology occurred half a century ago when James D. Watson and Francis Crick suggested a structure of deoxyribonucleic acid (DNA).

The term molecular biology first appeared in a report prepared for the Rockefeller Foundation in 1938 by Warren Weaver, then the director of the Foundation’s Natural Sciences Division.

It was to describe a research approach in which physics and chemistry would be used to address fundamental biological problems.

Some of the developments that have come to fruition in molecular biology since the 1950s originated in the area known as biochemical genetics.

In 2001, scientists announced the rough draft of the human genome sequence.
