Question

what are nucleotides concisely put

Answer 1

Nucleotides are the basic building blocks of nucleic acids, such as DNA and RNA. Each nucleotide consists of three components: a nitrogenous base (adenine, thymine, cytosine, guanine in DNA; adenine, uracil, cytosine, guanine in RNA), a five-carbon sugar (deoxyribose in DNA; ribose in RNA), and one or more phosphate groups. Nucleotides play key roles in storing and transferring genetic information, as well as in various biochemical processes such as energy transfer (e.g., ATP).
