Multiple choice

Proof reading and DNA repair are the characteristic functions of DNA polymerase I in prokaryotic replication. Identify the enzyme having the same function in eukaryotes.

In eukaryotic replication,  5 different kinds of polymerases have been demonstrated. They perform different functions.

  1. DNA polymerase α

  2. DNA polymerase β and DNA polymerase γ

  3. DNA polymerase γ

  4. DNA polymerase δ, DNA polymerase β and DNA polymerase ε

  5. DNA polymerase ε

D Correct answer
Explanation

DNA polymerase β is involved in the repair of DNA, and proof reading is done by DNA polymerase δ. DNA polymerase ε is involved in DNA synthesis on the lagging strand and the proof reading function.
