What is a nucleotide?

A type of monomer for proteins

A building block of DNA or RNA

A nucleotide is a fundamental building block of DNA and RNA, which are essential molecules in the storage and transmission of genetic information in living organisms. Each nucleotide consists of three components: a nitrogenous base, a five-carbon sugar (ribose in RNA and deoxyribose in DNA), and one or more phosphate groups.

In the structure of DNA and RNA, nucleotides join together to form long chains, allowing for the combination of sequences that code for proteins and other biological functions. The specific sequence of these nucleotides encodes the genetic information that dictates an organism's traits and functions. Understanding the role of nucleotides is crucial in genetics, molecular biology, and biochemistry, as they are vital for processes such as DNA replication, transcription, and translation.
