Verified by Experts

The correct Answer is:
A
In DNA, two helically twisted strands connected togher by steps. Each strand consists of alternating molecule of deoxyribose at 2'-position and phosphate groups. On the other hand, in RNA, the pentose sugar has an identical structure with deoxyribose sugar except that there is an -OH group instead of -H on carbon atom 2'. Hence it is only callled ribose.
