Which enzyme is not involved in DNA replication?
Correct answer: A. ribozyme
Ribozyme is a type of RNA with catalytic activity, playing a role in RNA splicing and modification. B: Unwinding enzyme (helicase) uses ATP to unwind the DNA double helix during DNA replication. C: Topoisomerase helps in unwinding, decatenating or relaxing the DNA during replication for proper coiling. D: Primase catalyzes the synthesis of short RNA primers which provide a 3′-OH end for DNA polymerase during DNA replication.
