Nucleotides are the building blocks of nucleic acids, which include DNA and RNA. They consist of three components: a nucleobase, a five-carbon sugar, and one or more phosphate groups. The nucleobase can be one of five types in DNA (adenine, thymine, cytosine, and guanine) or one of four types in RNA (adenine, uracil, cytosine, and guanine). The sugar component is either ribose in RNA or deoxyribose in DNA. The phosphate groups link nucleotides together to form the backbone of nucleic acids.

Nucleotides play a crucial role in various biological processes. They are the monomers that make up DNA and RNA, which are essential for genetic information storage and protein synthesis. Nucleotides also serve as coenzymes in metabolic reactions, acting as carriers of chemical groups in biochemical pathways. Additionally, nucleotides are involved in signal transduction and energy transfer within cells.

The study of nucleotides is important in fields such as molecular biology, biochemistry, and genetics. Researchers investigate the structure, function, and interactions of nucleotides to understand fundamental biological processes and develop new therapeutic strategies. For example, understanding the role of nucleotides in DNA replication and repair can lead to the development of targeted treatments for genetic disorders and cancer.
