Detailed explanation-1: -Phosphate Group in DNA Deoxyribonucleic acid (DNA) is made up of the building blocks called nucleotides. Each nucleotide comprises of three components such as a phosphate group, a nitrogenous base, and a deoxyribose.
Detailed explanation-2: -When two phosphate groups are linked to each other, the linkage itself is referred to as a ‘phosphate anhydride’, and the compound is called ‘inorganic pyrophosphate’ (often abbreviated PPi). The chemical linkage between phosphate and a carbon atom is a phosphate ester.
Detailed explanation-3: -Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.
Detailed explanation-4: -ADP, the “uncharged” version of the molecule, stands for adenosine diphosphate. The word diphosphate indicates that the molecule has 2 phosphate (PO3) groups.
