The amino acid sequence of cytochrome c is exactly the same in humans and chimpanzees. There is a difference of 13 amino acids between the cytochrome c of humans and dogs, and a difference of 20 amino acids between the cytochrome c of humans and rattle snakes. Which of the following is best supported by these data?
a. Rattlesnakes apparently gave rise evolutionarily to the dog, chimpanzee, and human.
b. Cytochrome c apparently has an entirely different function in rattlesnakes than in mammals, which explains the difference in the number of amino acids.
c. Cytochrome c is not found universally in animals.
d. Cytochrome c from a rattlesnake could function in a dog, but not in a chimpanzee.
e. The human is apparently more closely related to the chimpanzee than to the dog or rattlesnake.

Answer:

Option-(E): The human is apparently more closely related to the chimpanzee than to the dog or rattlesnake.                            

Explanation:

  1. Humans are primates and that s why we can argue that we are more closely related to the chimpanzees, as there are more similarities inside the genome and the sequences of the amino acids of the two species. And, thus they result in arrangement of both the species inside the same taxonomic level.
  2. While, the rattle snake and dog are far more different when it comes to the over all sequences of amino acid inside the living beings cellular structure.

A heme protein present within the outer and inner membrane of mitochondria is called Cytochrome c.

The main role is to transport electrons between the III complex and IV complex during ETC.

The correct answer is:

Option E. The human is apparently more closely related to the chimpanzee than to the dog or rattlesnake.

The explanation for this is:

  • Humans and Chimpanzees both are primates and are nearly related.

  • The genome and amino acid arrays of both animals are more comparable as correlated to any other mammal.

  • They come below the same taxonomical arrangement.

  • Rattlesnake being a reptile and dog being a mammal is different in amino acid sequences and are different in characters too.

Therefore, humans are closely related to chimpanzees than dogs or rattlesnakes.
