Sequence or positional information of amino acid is given by the
1 Secondary structure
2 Primary structure
3 Tertiary structure
4 Quaternary structure
Explanation:
The sequence of amino acids i.e., the positional information in a protein – which is the first amino acid, which is second, and so on – is called the primary structure.

Assertion : Haemoglobin is a quaternary protein. Reason : It consists of four amino acid unit.
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Quaternary structure is the fourth level of protein structure, which is not found in all proteins. It exists where two or more tertiary units also called a sub-unit combine to form one functioning protein. Eg: Molecule of Haemoglobin consists of four polypeptide chains i.e., two identical α-chains consisting of 141 amino acid residues and two identical β-chains consisting of 146 amino acid residues.Each chain is called a sub-unit and together they form the quaternary structure of the protein Haemoglobin. Therefore, the Assertion is true but Reason is false.

Select the correct option A. A protein thread does exist throughout as an extended rigid rod. B. Only some portions of the protein thread are arranged in the form of a helix.
1 Only A is correct
2 Only B is correct
3 Both are correct
4 Both are incorrect
Explanation:
A protein thread does not exist throughout as an extended rigid rod. The thread is folded in the form of a helix (similar to a revolving staircase).

Adult human haemoglobin consists of
1 4 subunits of beta
2 2 subunits (1-alpha,1-beta )
3 4 subunits (2-alpha, 2-beta)
4 4 subunits-alpha
Explanation:
Adult human haemoglobin consists of 4 subunits. Two of these are identical to each other. Hence, two subunits of α type and two subunits of β type together constitute the human haemoglobin (Hb).
