Detailed explanation-1: -The molecules that serve as the building blocks of DNA and RNA. Nucleotides consist of one nitrogenous base – adenine, cytosine, guanine, or thymine (uracil in RNA), a sugar (deoxyribose in DNA, ribose in RNA) and a phosphate group.
Detailed explanation-2: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
Detailed explanation-3: -The molecule’s ribonucleotide building blocks are themselves made up of three parts: a sugar molecule, a phosphate group and one of the four bases that form the alphabet of RNA’s genetic code-adenine, uracil, cytosine and guanine.
