What term denotes an error during replication?

Explanation:
Mutations are changes in the DNA sequence that can occur during replication when the DNA polymerase inserts the wrong nucleotide or slips, creating base substitutions, insertions, or deletions. If these errors are not repaired, they become permanent changes in the genome of the daughter cells. This is why the term for an error during replication is mutation. Transcription is the process of making RNA from DNA, not a change to the DNA itself; the double helix refers to DNA’s shape, and a polynucleotide is simply the polymer chain that makes up DNA.
