What does DNA stand for?

DNA stands for Deoxyribonucleic acid, which is the correct answer. This term is derived from the components that make up the DNA molecule. "Deoxyribo-" refers to the deoxyribonose sugar that is part of the DNA backbone, distinguishing it from ribonucleic acid (RNA), which contains ribose. The term "nucleic" refers to the fact that DNA is found in the nucleus of cells, and "acid" highlights its acidic properties due to the phosphate groups present in its structure.

Understanding the components of the name helps clarify how DNA functions and its role in genetics. This molecule carries the genetic instructions essential for the development, functioning, growth, and reproduction of almost all living organisms.
