What does DNA stand for?

DNA stands for Deoxyribonucleic Acid, which is the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. The term itself reflects the structure of the DNA molecule: it is composed of a deoxyribose sugar, phosphate groups, and nitrogenous bases. The correct answer highlights the complete and accurate terminology used in biology to describe this crucial component of life.

Understanding the structure is key; "deoxyribonucleic" refers to the sugar component (deoxyribose) and the nucleic part refers to its classification as a nucleic acid. This distinction is fundamental in genetics, molecular biology, and forensic science, reinforcing the importance of accurate scientific language.

The other options do not represent the correct terminology or components associated with DNA, either by misidentifying the sugar involved or by using incorrect descriptions for the molecular structure.
