Deoxy position of deoxyribose in DNA is at_____________.
A
(A) 1st carbon
B
(B) 2nd carbon
C
(C) 3rd carbon
D
(D) 5th carbon
Answer
(B) 2nd carbon
Explanation
Solution
Explanation:
Deoxy position of deoxyribose in DNA is at 2nd 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).
