Detailed explanation-1: -The order of enzymes in DNA replication include the following: DNA helicase, RNA primase, DNA polymerase, and finally DNA ligase. During the process of DNA replication, the double helix unwinds with the help of the enzyme DNA helicase.
Detailed explanation-2: -During DNA replications the enzymes are used in the following order: helicase, topoisomerase, RNA primase, DNA polymerase III, DNA polymerase I, DNA ligase.
Detailed explanation-3: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
Detailed explanation-4: -Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Detailed explanation-5: -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)
