Vertebrate myoglobins and hemoglobins each consist of units containing a heme group and an associated polypeptide chain. The polypeptide chains form an homologous series and can be compared with each other to measure amino acid differences and minimum base differences per codon. These differences are the result of mutations which have been incorporated… CONTINUE READING
