The Full Form of DNTP is‍ Deoxyribonucleotide Triphosphate.

A deoxyribonucleotide is a nucleotide that contains deoxyribose. They are the monomeric units of the informational biopolymer, deoxyribonucleic acid. Each deoxyribonucleotide comprises three parts: a deoxyribose sugar, a nitrogenous base, and one phosphoryl group. The nitrogenous bases are either purines or pyrimidines, heterocycles whose structures support the specific base-pairing interactions that allow nucleic acids to carry information. The base is always bonded to the 1′-carbon of the deoxyribose, an analog of ribose in which the hydroxyl group of the 2′-carbon is replaced with a hydrogen atom. The third component, the phosphoryl group, attaches to the deoxyribose monomer via the hydroxyl group on the 5′-carbon of the sugar.
