The diagram shows a nucleic acid in the shape of a helix. which sugar is present in the nucleic acid that is represented in the diagram? a) uracil b) thymine c) deoxyribose d) ribose

The correct answer is C) Dexyribose

The correct answer is d) ribose

Explanation:

The diagram represents a molecule of RNA (ribonucleic acid) because its contains the nitrogenous bases C (Cytosine) , G (Guanine) , A (Adenine) and U (Uracil). Uracil is only present in RNA molecules, and it replaces Thymine (present in DNA molecules). Unline DNA molecules, RNA contains ribose sugars which have -OH groups attached to each carbon in the sugar ring structure. In contraposition, DNA contains deoxyribose sugars, which lack one oxygen atom in 2' position of the sugar ring.
