DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides. Each nucleotide consists of three components:
Nucleic acids are the molecules that carry the genetic information that is passed down from parent to child. However, nucleic acids are special since they can also combine with proteins to become the machines -- called ribosomes -- that turn genetic instructions in nucleic acids into other protein machines. Nucleic acids are linked together into a chain. DNA is made of two chains that connect like a rope ladder.
