Question

Quizplus · Accepted Answer

Proofreading of DNA occurs in the 3' to 5' direction, where the DNA polymerase checks each newly added nucleotide against the template strand before adding the next nucleotide. This ensures that the new nucleotide is correctly base-paired with the template strand before the next nucleotide is added. Proofreading in the 5' to 3' direction does not occur during DNA replication.
