What does DNA stand for?

DNA stands for Deoxyribonucleic acid. This term reflects the molecular structure of DNA, which is composed of two key components: deoxyribose sugar and nucleic acid. Deoxyribose is a sugar that has one less oxygen atom compared to ribose, which is pivotal in determining the structure and function of DNA. The "nucleic acid" part indicates that DNA is one of the types of nucleic acids that serve as the building blocks of life, responsible for storing and transmitting genetic information in organisms.

The other options do not accurately describe DNA. For example, "Deoxyribonucleic atom" incorrectly refers to an atom rather than a complex molecule made of atoms. "Dynamic nucleic acid" lacks the essential focus on the specific sugar component, and "Deoxyribonucleus acid" misrepresents the term by incorrectly merging 'nucleus' into the terminology, which is not a recognized component of DNA’s name. Understanding the full term helps clarify the role and importance of DNA in biology.
