What does DNA stand for?

The correct answer, which is "Deoxyribonucleic acid," accurately describes the full name of DNA. This term is composed of several components: "deoxy" refers to the absence of an oxygen atom in the ribose sugar, "ribo" indicates that it is related to ribose, "nucleic" pertains to the nucleic acids, and "acid" denotes the acidic nature of the phosphate group present in the molecule. Together, these components provide a precise description of the structure and function of DNA as the molecule that carries genetic information in living organisms.

The alternative choices provide variations of the name that either omit critical components or slightly alter them, which makes them less accurate in defining DNA. It's essential to use the correct terminology to ensure clarity and precision in the field of molecular biology. Understanding the full name helps in recognizing the structural intricacies of DNA that are central to genetics and biochemistry.
