Definition of oligonucleotide in English:

noun

• A polynucleotide whose molecules contain a relatively small number of nucleotides.

  Example sentences

  • ‘Probes are typically fairly short sequences of DNA nucleotides, called oligonucleotides, made synthetically.’
  • ‘Intermolecular tetrameric complexes are usually only formed by short oligonucleotides that contain single tracts of contiguous guanines.’
