Assertion : The long protein chain is folded upon itself like a hollow ball giving rise to the tertiary structure .
Reason : Tertiary structure gives a 3-dimensional view of a protein.

A : If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.
B: If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C : If Assertion is true but the Reason is false.
D :If both Assertion and Reason are false.

Answer

B

Explanation

The primary structure of proteins is the sequence of amino acids in a chain, i.e., the positional information in a protein. In the secondary structure protein thread is folded in the form of a helix or in the sheet form. The long protein chain is also folded upon itself like a hollow woollen ball, giving rise to the tertiary structure. This gives us a 3-dimensional view of a protein. Tertiary structure is absolutely necessary for many biological activities of proteins.
