oligonucleotide (rus. олигонуклеотид) — a short nucleotide chain of up to 20-30 bases.


Nucleotides are components of nucleic acids consisting of a nitrogenous base, carbohydrate residue and a phosphate group. Short and long nucleotide sequences (polynucleotides) have no specific quantitative boundary; their classification is rather relative. Synthetic oligonucleotides (primers, probes, etc.) are widely used in molecular biology, genetic engineering and biotechnology, as well as for molecular diagnostics in medicine.
