Assertion : The bonds attaching second and third phosphated in higher nucleotide are high energy bonds
Reason : The bonds are attached against force of repulsion.

Options

A. If both the asseration and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and rreason are true but the reason not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If the assertion is false but reason is true

Answer

A

Explanation

(a) Nucleotids having more than one phosphate group are called higher nucleotides. The second and third phosphates of higher nucleotides are attached against forces of repulsion between similarly charged phosphate resicals. Hence, the bonds attaching second and third phosphates are higher energy bonds.
