Which carbon atom of deoxy Ribose sugar in D N A does NOT contain C-OH bond (A) C_{5} (B) C_{3} (C) C_{2} (D) C_{1}
Which carbon atom of deoxy Ribose sugar in D N A does NOT contain C-OH bond (A) C_{5} (B) C_{3} (C) C_{2} (D) C_{1}

Correct option is C

Deoxyribose is a five-carbon-atom pentose sugar. The ring’s four carbon atoms are numbered 1′, 2′, 3′, and 4′. – CH2OH has a carbon atom with the number 5′. At positions 1′, 3′, and 5′, there are three —OH groups. Carbon atoms 1′, 2′, 3′, 4′, and 5′ have hydrogen atoms connected to them. In DNA, the one carbon atom at C2 of deoxyribose sugar does not have a —C—OH link.
