A single base change can create a devastating genetic disorder or a beneficial adaptation, or it might have no effect.

For example, sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced.

25 окт. 2016 г. · These changes within DNA are called point mutations because only one nucleotide is substituted, added, or deleted (Figure 17.5. 1).
