Question

The proofreading function of DNA polymerase involves all of the following except:a. reversal of the polymerization reaction. b. phosphodiester bond hydrolysis. c. detection of mismatched base pairs. d. base pairing. a 3' --> 5' exonuclease.

Answer 1

Reversal of the polymerization reaction.

Step-by-step explanation:

DNA polymerase may be defined as the enzyme that are responsible for the synthesis of the DNA molecule. Single DNA polymerase is present in prokaryotes whereas three different DNA polymerase is present in eukaryotes.

The DNA polymerase has the ability to break the phosphodiester bond and can detect the incorrect match pair and plays an important role in the DNA repair process. This enzyme has the ability to acts as an exonuclease as well. The polymerization reaction cannot be reversed by the DNA polymerase and other specific enzymes require for this process.

Thus, the correct answer is option (a).
