Question

The enzyme DNA polymerase was discovered by _________.

• A. Kornberg
• B. Okazaki
• C. Watson and Crick
• D. Stahl and Meselson
• E. Jacob and Monod

Answer 1

The correct option is A Kornberg

Arthur Kornberg purified and characterized DNA polymerase from E. coli cells which are encoded by the polA gene. It catalyzes phosphoryl group transfer. The 3-hydroxyl group of the nucleotide at the 3'-end of the growing strand serves as a nucleophile for nucleophilic attack at the $\alpha$-phosphorus of the incoming deoxynucleoside triphosphate. Inorganic pyrophosphate is released in the reaction.

So, the correct answer is option A.
