DNA stands for?

Explanation:
DNA stands for deoxyribonucleic acid. The name reveals its chemistry: "deoxy" means the sugar in its backbone lacks an oxygen atom at the 2' carbon, "ribo" refers to ribose—the five-carbon sugar used in nucleotides—though in DNA it is in the deoxy form, and "nucleic acid" places it in the family of molecules composed of nucleotides that store genetic information. The other options don’t fit because RNA uses ribonucleic acid, not deoxyribonucleic; the standard term is "deoxyribonucleic acid" rather than "deoxyribose nucleic acid"; and simply "nucleic acid" is too general to specify DNA.
