What does DNA stand for?

DNA stands for Deoxyribonucleic acid, which accurately describes the molecular structure of this essential biomolecule. The term encompasses both the sugar component, deoxyribose, and its role as a nucleic acid. DNA is the hereditary material in almost all organisms, and it carries the genetic instructions necessary for the growth, development, reproduction, and functioning of living beings.

The name reflects both its chemical composition and its function. The "deoxy" refers to the absence of one oxygen atom in the ribose sugar compared to ribonucleic acid (RNA), while "nucleic acid" indicates its existence in the nucleus of eukaryotic cells. Understanding the full name helps underscore the importance of DNA in genetics and molecular biology.
