Why do chromosome mutations occur most often during nuclear divisions?
Chromosome mutations occur during nuclear division because when the sequence of nucleotides are being placed substitutions, and frameshifts can occur, causing mutations. Substitution is when one nucleotide replaces another and frameshift mutation is when a nucleotide deletes, causing codons to be incorrectly read.
