1.

At which phase of the cell cycle, DNA polymerase activity is at its highest?(a) Gap 1 (G1)(b) Mitotic (M)(c) Synthetic (S)(d) Gap 2 (G2)

Answer»

Answer is : (c) Synthetic (S)

DNA polymerase is an enzyme that synthesises DNA molecules from deoxyribonucleotides, the building blocks of DNA. These enzymes are essential for DNA replication. S-phase or synthetic phase is significant due to DNA synthesis. Thus, DNA polymerase activity is highest at S-phase of cell cycle.
