The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.
Nucleotide - Wikipedia
Nucleotide (abbreviated "nt") is a common unit of length for single-stranded nucleic acids, similar to how base pair is a unit of length for double-stranded nucleic acids. Nucleotide supplements.

What is a Nucleotide - BiologyWise
A nucleotide is a monomer which is a building block of RNA and DNA. Nucleotide plays a vital role in the metabolic process and can be considered as the source of energy in our body.
Nucleotide - National Center for Biotechnology Information
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
3 Parts of a Nucleotide and How They Are Connected
A free nucleotide may have one, two, or three phosphate groups attached as a chain to the 5-carbon of the sugar. When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond to the 3-carbon of the sugar of the next nucleotide, forming the sugar-phosphate backbone of the nucleic acid.
