DNA stands for which compound?

DNA stands for which compound?

• A. Deoxyribonucleic Acid
• B. Ribonucleic Acid
• C. Deoxyribonucleolar Acid
• D. Ribonucleic Deoxynucleic Acid

Answer: (A)

The main idea here is understanding what the abbreviation DNA represents and how its parts describe the molecule. DNA stands for deoxyribonucleic acid. The word pieces reflect its structure: deoxy points to deoxyribose, a sugar missing one oxygen compared with ribose; ribo refers to that sugar family; nucleic indicates it belongs to nucleic acids involved in genetic information; and acid classifies it as an acid macromolecule. This naming specifically identifies DNA as a nucleic acid with deoxyribose, distinguishing it from RNA, which is ribonucleic acid. The other phrases mix up those terms, so they don’t correctly name the molecule.
