Proofreading, DNA Polymerase I and DNA Polymerase III
|
Detailed explanation-1: -In the final stage of DNA replication, the enyzme ligase joins the sugar-phosphate backbones at each nick site. After ligase has connected all nicks, the new strand is one long continuous DNA strand, and the daughter DNA molecule is complete.
Detailed explanation-2: -DNA polymerase III (It is the main replicating enzyme) Helicase (separate double-stranded DNA into single strands allowing each strand to be copied)
Detailed explanation-3: -A special enzyme, DNA ligase (shown here in color), encircles the double helix to repair a broken strand of DNA. DNA ligase is responsible for repairing the millions of DNA breaks generated during the normal course of a cell’s life.
Detailed explanation-4: -In bacteria, all three DNA polymerases (I, II and III) have the ability to proofread, using 3’
