WebAnother way that mutations can happen if the DNA gets damaged and isn't repaired properly. This damage could be from x-rays, UV radiation, or mutagenic chemicals. They tend to cause different types of damage, which is repaired in different ways. WebJul 1, 2024 · This single missing or added nucleotide causes a frameshift mutation which throws off the entire reading frame of the amino acid sequence and mixes up the codons. This usually does affect the amino acids that are coded for and change the resulting protein that is expressed.
