description Arthur Kornberg Overview

Arthur Kornberg was a pioneering American biochemist whose research fundamentally advanced our understanding of DNA synthesis. He identified T4 DNA polymerase, an enzyme capable of creating new DNA strands, a discovery that revolutionized molecular biology. This work earned him the 1959 Nobel Prize in Physiology or Medicine and remains critically important for scientists studying genetics, heredity, and disease. His contributions are essential for researchers in academia and biotechnology focused on DNA research.

help Arthur Kornberg FAQ

Did Arthur Kornberg discover T4 DNA polymerase?

No. Kornberg is best known for isolating DNA polymerase I from Escherichia coli in 1956. T4 DNA polymerase is a different enzyme from a bacteriophage and should not be credited to Kornberg.

Why did Arthur Kornberg win the 1959 Nobel Prize?

He shared the Nobel Prize in Physiology or Medicine with Severo Ochoa for discovering mechanisms involved in the biological synthesis of DNA and RNA. Kornberg's work centered on enzymes that build DNA strands.

What does DNA polymerase I do?

It uses a template strand and nucleotides to extend a new DNA strand, while also helping remove and replace certain primer sections. Kornberg's E. coli enzyme gave researchers a powerful laboratory model for studying DNA synthesis.

Is Arthur Kornberg related to Roger Kornberg?

Yes. Roger Kornberg is Arthur Kornberg's son and won the 2006 Nobel Prize in Chemistry for work on the molecular basis of eukaryotic transcription.
