During DNA replication, events at the replication fork require different types of enzymes having specialized functions except:
|
|
DNA gyrase
|
|
|
DNA polymerase III
|
|
|
DNA ligase
|
|
|
DNA glycosylase
|
Explanation:
Detailed explanation-1: -What Happens at the Replication Fork? Two main activities happen at the fork: DNA unwinding and DNA synthesis. The RF unwinds the unreplicated DNA ahead of it through a helicase enzyme complex (Gambus et al. 2009; Lou et al.
Detailed explanation-2: -DNA Polymerase is the main enzyme in the replication process.
Detailed explanation-3: -DNA polymerase III (It is the main replicating enzyme) 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)
