Which of the following enzymes are essential for DNA replication in an animal cell?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Topoisomerase, DNA ligase, DNA polymerase, DNA primase.
The essential enzymes for DNA replication in an animal cell include topoisomerase, DNA ligase, DNA polymerase, and DNA primase. Each enzyme plays a critical role: topoisomerase relieves tension, ligase joins fragments, polymerase synthesizes new DNA, and primase lays down RNA primers.
