Question

Correct statements describing DNA polymerase I include which of the following?
a. It can add deoxyribonucleoside triphosphates to the 3'-hydroxyl end of a DNA primer chain.
b. It can act as an endonuclease in DNA repair
c. It can act as a 5' to 3' exonuclease
d. It is the major polymerizing enzyme in the replication process.​

Answer 1

Answer:

DNA polymerase is an enzyme used in the replication of DNA. It ads the DNA primers to the parent chain. This enzyme acts in the 5'-3 direction and thus forms lading stand on the chain that has 3'5' direction.

There are 3 DNA polymerases in use from which only the DNA polymerase II helps in replication and rest of the two are used in the DNA proofreading.

So, the correct option is 'It adds RNA nucleotides along the DNA template in transcription.'
