Question

Deoxyribonucleoside triphosphates serve dual purposes in DNA replication. In addition to acting as substrate, the other function is similar to?

• A. DNA polymerase
• B. rRNA
• C. Topoisomerase
• D. ATP

Answer 1

The correct option is D ATP

Answer :

i) The Deoxyribonucleoside Triposphate act as both energy (ATP) and substrate for the polymerization reaction.

ii) The Deoxyribonucleoside Triposohate (DTPs) is considered as the building block of DNA synthesis.

iii) The DTPs possess two high-energy phosphate that has the ability to provide energy to the replication by breaking their molecules.

iv) It serves as a substrate that is consumed during the enzymatic reaction of replication.

So correct answer is option D.ATP.
