Unit 2—DNA Mutation-a ‘mistake’ in DNA caused by genetic and/or environmental factors Insertion/deletion-the number of nitrogen bases is incorrect and the entire strand of DNA is changed after the mutation because all codons get shifted Substitution-one nitrogen base is incorrect and this only changes one amino acid in the protein that is made
