Question

Every $\alpha$ or $\beta$ chain of haemoglobin have

• A. Tertiary structure
• B. Quarternary structure
• C. Secondary structure
• D. Primary structure

Answer 1

The correct option is A Tertiary structure

The hemoglobin molecule is made up of four polypeptide chains: two alpha chains < >of 141 amino acid residues each and two beta chains < > of 146 amino acid residues each. The alpha and beta chains have different sequences of amino acids, but fold up to form similar three-dimensional structures.

So, the correct option is 'Tertiary structure'.
