Question

Deoxy position of deoxyribose in DNA is at_____________.

• (A) $1^{\text{st }}$ carbon
• (B) $2^{\text{nd }}$ carbon
• (C) $3^{\text{rd }}$ carbon
• (D) $5^{\text{th }}$ carbon

Answer 1

The Correct Option is B

Explanation:
Deoxy position of deoxyribose in DNA is at $2^{\text{nd }}$ carbon.The combination of these molecules makes the building blocks for DNA synthesis. The sugar present in the DNA is $2$'deoxyribose, a five-carbon monosaccharide, which is devoid of oxygen in its $2$' position, hence the name deoxyribonucleic acid.Hence, the correct option is (B).
