Long description

Part (a) shows the normal sequence of DNA within a gene. This sequence codes for a sequence of amino acids within a protein. Each amino acid is represented as a blue block on a chain. Part (b) shows a mutation in the DNA sequence from part (a). This change is highlighted in orange. The amino acid sequence coded by this DNA sequence is shown. Amino acids are shown as blue blocks on a chain. The amino acid altered by the mutation is shown in brown.
