Question

PLZ HELP The diagram below shows a segment of the amino acid sequence from the hemoglobin protein from several organisms

Answer 1

Answer:

B. The chimp and human are the most closely related organisms with the fewest differences in their amino acid sequence

Explanation:

This question shows a table containing the amino acid sequence of haemoglobin protein in different organisms. According to the table attached, a total of 15 amino acids are represented for each organism. A very reliable evidence that shows the relationship between organisms i.e. how related they are, is their DNA SEQUENCE.

Since the amino acid sequence of the protein in an organism is determined by the DNA sequence, organisms with very similar amino acid sequence are said to be CLOSELY RELATED. Hence, the similar the DNA sequence, the closer the relationship between organisms. In this case, the chimp and human have the same set of amino acids in their sequences, hence, they are the most closely related organisms with the fewest differences in their amino acid sequence.
