Explanation:
Detailed explanation-1: -DNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading.
Detailed explanation-2: -The enzyme responsible for proofreading during replication is called DNA polymerase. DNA polymerase takes an ‘unzipped’ DNA strand and adds in the appropriate nucleotide bases to make two complete double-helix strands.
Detailed explanation-3: -In bacteria, all three DNA polymerases (I, II and III) have the ability to proofread, using 3’
