Case Leonard · Answer 1

Answer: D. The DNA sequences for the cytochrome c genes in chimpanzees and spider monkeys are over 90% identical.

Cytochrome c gene encodes for a protein that is very common among primates. This gene does not have undergone much changes during the process of evolution. Cytochrome c is a respiratory pigment found in the mitochondria of eukaryotes.

Carlos Gould · Answer 2

The answer is option D.

Explanation:

The DNA arrangements for the cytochrome c qualities in chimpanzees and creepy crawly monkeys are more than 90% identical. Cytochrome c quality encodes for a protein that is extremely basic among primates. This quality does not have experienced much changes amid the procedure of advancement. Cytochrome c is a respiratory shade found in the mitochondria of eukaryotes.
