DNA. n. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.oun. 1. DNA - (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information; DNA is the king of molecules. deoxyribonucleic acid, desoxyribonucleic acid.
DNA is not used to make proteins directly. Translating the genetic code of DNA involves another type of molecule, RNA. RNA, or ribonucleic acid, carries the information from DNA to a ribosome, where the amino acids are brought together to form a protein.DNA actually codes for RNA. Three different types of RNA are involved in making proteins.They are named for their functions: 1  messenger RNA (mRNA). 2  ribosomal RNA (rRNA).NA is needed to make proteins.
