Deoxyribonucleic acid (/diËÉksiËraÉªbÉµ.njuËËkleÉª.É¨k ËaesÉªd/ ; ËÃ¦SÉªD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. viruseshe two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase âeither cytosine (C), guanine (G), adenine (A), or thymine (T)âas well as a monosaccharide sugar called deoxyribose and a phosphate group.
Mitochondrial DNA is a special type of DNA and many people are not even aware this type of DNA actually exists. The human cell has two type of DNA: Nuclear DNA and Mitochondrial DNA. We even have 2 separate genomes â the nuclear DNA genome (which is linear in shape) and the Mitochondrial DNA genome (which is circular). Mitochondrial DNA is pretty basic in that it only contains 37 genes.
