Which of the Following Mammalian Cell DNA Polymerases is Not

Question

Which of the following mammalian cell DNA polymerases is not correctly matched with its function?
A)DNA Pol$\alpha$-priming DNA synthesis
B)DNA Pol $\beta$-DNA repair
C)DNA Pol $\gamma$-elongation of both strands
D)DNA Pol   $\delta$ -ligation of DNA strands
E)DNA Pol $\varepsilon$-DNA repair

Accepted Answer

DNA Pol δ is primarily involved in elongation of both strands during DNA replication, while DNA ligation is carried out by a separate enzyme called DNA ligase. Therefore, the pairing of DNA Pol δ with the function of ligation of DNA strands is not correct.
