Detailed explanation-1: -The second part of a nucleotide is the phosphate, which differentiates the nucleotide molecule from a nucleoside molecule. This phosphate is important in the formation of phosphodiester bonds, which link several nucleotides in a linear fashion.
Detailed explanation-2: -In organic systems, the phosphate molecule is the form that bodily phosphorus is used mainly in the form of nucleic acids DNA and RNA and the nucleotides that form them.
Detailed explanation-3: -Phosphorus is an essential component of all cells; the element forms the backbone of nucleic acids, without which cells cannot reproduce. Phosphorus is also incorporated in nucleotides, sugars, proteins, and lipids.
Detailed explanation-4: -Each nucleotide consists of: a phosphate group, which contains phosphorus and oxygen (PO4). a sugar, which is deoxyribose (C5H8O4) in DNA and ribose (C5H10O5) in RNA.
Detailed explanation-5: -The three components of a nucleotide are a nitrogenous base, a pentose sugar, and a phosphate group. Without a phosphate group, the molecule is called a nucleoside. Nucleotides with two or three phosphates are called nucleotide diphosphates and nucleotide triphosphates, respectively.
