Venkatraman Ramakrishnan, Biography, Education, Awards

Venkatraman Ramakrishnan is an Indian-born American-British structural biologist who received the 2009 Nobel Prize in Chemistry jointly with Thomas A. Steitz and Ada E. Yonath for their studies on the structure and function of the ribosome. His scientific journey is notable for his transition from physics to biology and his pioneering work in understanding the ribosome at the atomic level.

Venkatraman Ramakrishnan Biography

Venkatraman Ramakrishnan was born in 1952 in Chidambaram, Tamil Nadu, an ancient temple town known for the Nataraja Temple. His father, C. V. Ramakrishnan, was a scientist, while his mother, R. Rajalakshmi, taught at Annamalai University. During his childhood, his family spent periods in India and abroad because of his parents’ academic and research commitments.

Ramakrishnan initially pursued physics, but his scientific interests gradually shifted towards biology. This transition ultimately led him to the study of ribosomes, one of the most important molecular machines in living cells.

Venkatraman Ramakrishnan Education

Ramakrishnan completed his Bachelor’s degree in Physics from Baroda University in 1971. He later moved to the United States and obtained a PhD in Physics from Ohio University in 1976.

After completing his doctorate, he recognised that he needed a stronger foundation in biology to pursue the questions that interested him. He therefore spent about two years studying biology at the University of California, San Diego.

This change in academic direction became an important turning point in his career. Rather than remaining confined to one discipline, he combined knowledge from physics, biology, biophysics and structural biology.

From Physics to the Study of Ribosomes

Ramakrishnan’s interest in ribosomes began during his postdoctoral work at Yale University in the laboratory of Peter Moore in the late 1970s. He joined the ribosome research project in 1978, beginning a scientific journey that would eventually lead to the Nobel Prize.

At Yale, he learned specialised techniques for working with ribosomes, including their purification, reconstitution and analysis. These methods later became extremely valuable when his research group began attempting to determine the structure of the ribosomal subunit.

What Is a Ribosome?

A ribosome is a complex molecular structure found in all living cells that is responsible for protein synthesis. It reads the genetic information carried by messenger RNA (mRNA) and uses it to assemble amino acids into proteins. Ribosomes consist mainly of ribosomal RNA (rRNA) and proteins and have two subunits that work together during translation. They are also important targets for several antibiotics, which inhibit bacterial protein synthesis.
