Mutations Gene alterations Involve the inclusion of a wrong amino acid 5/13/2019 Mutations Gene alterations Involve the inclusion of a wrong amino acid Point mutation 1. Changing one nucleotide Sickle cell anemia Silent mutation (no change in amino acid) 2. Deletion Loss of a nucleotide or segment of DNA Frameshift mutation
