DNA stands for

DNA stands for

• A. Ribonucleic acid.
• B. Deoxyribose nucleic acid.
• C. Nucleic acid.
• D. Deoxyribonucleic acid.

Answer: (D)

DNA stands for Deoxyribonucleic acid. The deoxy part points to deoxyribose, the five‑carbon sugar in DNA that lacks one oxygen compared with the sugar in RNA. The ribo component links to ribose, tying DNA to the same family of sugars used in nucleic acids. The nucleic part signals that this molecule is built from nucleotides and belongs to the group of nucleic acids, while the acid ending reflects the phosphate backbone that gives these molecules their acidic character. This naming also helps distinguish DNA from RNA, which is ribonucleic acid and uses ribose. The other options either refer to RNA, describe only a general class, or replace the canonical term with an imperfect sugar name, so the full designation Deoxyribonucleic acid is the correct one.
