Question

A. The amino acids in the β chain of haemoglobin in Chimpanzee and human are the same. B. The difference in amino acids in the β chain of haemoglobin in rats and human beings is just one amino acid. C. Gorilla, chimpanzee and humans also have the same amino acids in the β chain of haemoglobin. Which of the above are False?

• A. Only A
• B. Only C
• C. Both B and C
• D. A, B and C

Answer 1

The correct option is C Both B and C

Haemoglobin, the respiratory pigment in man, chimpanzee, gorilla and rat contains 2 α chains and 2 β chains of amino acids. When a comparison study was done, we found out that the amino acids in the β chain of haemoglobin in Chimpanzee and human are the same. But there is a difference of 31 amino acids when a rat and a human being is considered. Similarly, considering the case of gorilla and humans, we find that there is a difference of 1.
