Question
Shown below are two homologous lengths of the a and b chains of human hemoglobin. Consult the genetic code dictionary and determine how many amino acid substitutions may have occurred as a result of a single-nucleotide substitution. For any that cannot occur as the result of a single change, determine the minimal mutational distance.
1. The change from Ala - Gly requires five changes.
2. The change from Pro - Lys requires two changes.
3. The change from Val - Leu requires two changes.
5. The change from Pro - Lys requires three changes.

Diverse amino acids are coded by distinctive triples of nucleotides in DNA of the genes, this code is currently known. Most mutation includes substitutions of single nucleotides some place in DNA chain coding for a given protein. Subsequently one can figure the base number of single mutations expected to change the cytochrome C of one life form into that of another.
