The Genius of Arthur Kornberg: Unraveling the Secrets of DNA Replication

Have you ever wondered how DNA, the blueprint of life, is replicated in our bodies? Decades ago, scientists were puzzled about this and searched for answers to unlock this mystery. One of the greatest scientific minds who contributed to solving this puzzle was Arthur Kornberg.

Arthur Kornberg was a renowned biochemist who was awarded the Nobel Prize in Medicine in 1959 for his groundbreaking work in DNA replication. He dedicated his life to understanding how DNA was replicated in living cells, and his work paved the way for significant advancements in the field of genetics.

Let’s take a closer look at the life and work of this remarkable scientist in 8 sections:

Early Life and Education

Arthur Kornberg was born in 1918 in New York City, USA, to Jewish immigrants from Eastern Europe. His father was a peddler, and his mother was a homemaker. Despite their limited financial resources, they encouraged their son’s academic endeavors.

Arthur studied at City College of New York, where he received a Bachelor of Science degree in science in 1937. Later, he attended the University of Rochester Medical School, where he earned his Doctor of Medicine degree in 1941.

Discovery of DNA Polymerase

After completing his medical degree, Kornberg began his research career at Washington University School of Medicine in St. Louis. In 1956, he discovered an enzyme called DNA polymerase, which played a crucial role in DNA replication. This discovery was historic as it was the first time a scientist had isolated an enzyme responsible for DNA synthesis.

The role of DNA polymerase is to add nucleotides to the growing DNA chain from one end. This process requires a “primer” from which the polymerase can start adding nucleotides. Kornberg’s discovery of DNA polymerase revolutionized the study of DNA replication and laid the foundation for future research in this area.

Enzymatic Synthesis of DNA

Kornberg’s research showed that DNA replication in living organisms could be carried out outside cells through enzymatic synthesis. He was the first person to synthesize DNA in vitro by using purified DNA polymerase and various nucleotides.

This discovery allowed the production of artificial DNA for research purposes and aided in the development of recombinant DNA technology, essential to the biotech industry today.
