Which organism has the least difference in the number of amino acids in cytochrome c compared to humans? Which organism has the greatest difference? Dog, turtle, frog, tuna, silkworm, rhesus monkey, kernel of wheat, yeast cell.
Cytochrome c has changed very slowly during evolution. The amino acid sequence between humans and chimpanzees are identical while between the rhesus monkey, there is a difference of one amino acid in comparison. This table shows that the amino acid sequence compared from humans are more closely related to chimpanzees.
