Caption

Cystic fibrosis, sickle cell anemia, Huntington's disease and phenylketonuria are all examples of disorders caused by the mutation of a single nucleotide, a building block of DNA. The human DNA consists of approximately 3 billion nucleotides of four types: Adenine (A), cytosine (C), guanine (G), and thymine (T). In some cases, the difference of just one nucleotide can bring serious consequences. Scientists hope to cure these diseases by substituting the incorrect nucleotide with the correct one.
