What does DNA stand for?

DNA stands for Deoxyribonucleic Acid, which reflects its structure and components. The term "deoxyribo" signifies that the sugar in the DNA backbone is deoxyribose, a five-carbon sugar that lacks one oxygen atom compared to ribose, the sugar found in RNA. The "nucleic" part indicates that DNA is a type of nucleic acid, which plays a critical role in storing and transmitting genetic information. Lastly, "acid" refers to the phosphate group present in the nucleotide structure, which gives DNA its acidic properties.

Understanding the full term is important as it encapsulates the essential characteristics of this molecule, which is crucial for biological inheritance, as it serves as the blueprint for all living organisms. The other terms provided do not accurately represent the structure or function of DNA, thereby leading to a misunderstanding of this fundamental biological molecule.
