Question

During dna replication in a human cell, 6 billion bases must be paired properly. which characteristic of dna best allows for high levels of accuracy during this process?

Answer 1

DNA polymerase III has a subunit for proofreading during DNA replication. As replication continues and the polymerase III enzyme detects a mismatched base pair, through a deformity in the double helix structure, the polymerase backs up, nicks the mismatched base and replaces it with the correct base before continuing replication.   

Answer 2
