Description
The genetic information of an organism is stored and inherited as nucleic acids. Deoxyribonucleic acid, in short DNA, is a huge molecule (macromolecule). It is assembled as a double helix made up of two chains of nucleotides. The double helix structure can be thought of as a twisted rope ladder. The ladder‘s backbone is made of three components: sugar, phosphate and the rungs consist of base pairs, either adenine and thymine or guanine and cytosine.
