Detailed explanation-1: -Explanation: DNA helicase unwinds the double helix, separating the two strands so they may be replicated by DNA polymerase. Primase adds an RNA primer to help initiate DNA replication. DNA ligase is responsible for joining Okazaki fragments on the lagging strand during replication.
Detailed explanation-2: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
Detailed explanation-3: -Helicase (separate double-stranded DNA into single strands allowing each strand to be copied) DNA gyrase (reduces supercoiling which builds up during DNA unwinding) DNA ligase (Joins the discontinuously synthesized fragments)
Detailed explanation-4: -Both helicase and DNA polymerase are involved in DNA replication, but the enzymes perform different functions within the replication process.
