What does DNA stand for?

The correct answer is that DNA stands for Deoxyribo Nucleic Acid. This term accurately describes the structure and components of DNA.

The "Deoxy" refers to the sugar component, which is deoxyribose, a modified sugar that lacks one oxygen atom compared to ribose, which is found in RNA. The "Ribo" part is indeed part of the name of the sugar, reflecting its structural similarity to ribose. The "Nucleic" indicates that it is found within the nucleus of cells, where it is housed, while "Acid" signifies its acidic properties, which are due to the phosphate groups that form part of its structure.

Other options provided do not accurately convey the correct terminology or structure of DNA. For instance, "Deoxyribose Nucleic Acid" omits the essential reference to "Acid," which is crucial in naming nucleic acids like DNA. "Deoxynucleic Acid" misses the specificity of the sugar component, which is important for distinguishing between the types of nucleic acids. Lastly, "Dioxy Ribo Nucleic Acid" contains an incorrect prefix "Dioxy" that does not reflect the actual chemistry of the nucleic acid
