WebDNA is a molecule composed of two strands that coil around each other to form a double helix. Each strand is made up of a string of molecules called deoxyribonucleotides (dNTPs). Each dNTP contains a phosphate group, a sugar group, and one of four nitrogenous bases [adenine (A),thymine (T), guanine (G), or cytosine (C)]. WebBecause sequencing is a derivative form of DNA replication, sequencing reactions require a template, a primer, the four deoxyribonucleoside triphosphate (dNTP) building blocks, and a DNA polymerase.
