a polymer composed of more than three nucleotides.

A DNA polymer composed of only a few nucleotides.

A short sequence (usually 2-50 bases) of DNA or RNA.

A molecule consisting of a small number of nucleotide units.

Oligonucleotide is a compound made up of the condensation of a small number of nucleotides.

A very short length of a nucleic acid molecule.

A short DNA or RNA molecule.

A chain of a few nucleotides.

a long linear sequences of nucleotides

an oligomer resulting from a linear sequences of nucleotides

a nucleic acid polymer composed of two or more nucleotides or nucleotide analogues

short sequence of nucleic acid, containing a small number of nucleotides

A short nucleic acid molecule; normally refers to molecules between 5 and 200 nucleotide residues(bases) long.

A segment of DNA, a string of nucleotides (Ford, 1997).

A nucleic acid segment comprising a few nucleotides.

Short nucleic acid of up to about 20 nucleotides.

A polymer chain of several nucleotides

a short chain of nucleotides.

a short sequence (usually between 10-100 nucleotides) of DNA.

a sequence of nucleotides, the building blocks of DNA.

A polymer consisting of a small number (about two to ten) of nucleotides.

A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer. See also: nucleotide

Short chain of nucleic acid monomers.

("oligo" means few) A short length of DNA nucleotides, often used as primers for DNA synthesis or probes for arrays and ISH/FISH; usually referred to as "oligo(s)."

A chain of usually up to 20 nucleotides

A short sequence of polynucleotide. Oligonucleotides with a defined sequence can synthesized in vitro for use for a variety of techniques, including PCR, DNA sequence analysis, hybridization, and site-directed mutagenesis. The length of an oligonucleotide is described as a #-mer -- for example, an oligonucleotide with 20 nucleotides would be called a 20-mer).

A short molecule consisting of several linked nucleotides (typically between 10 and 60) chained together and attached by covalent bonds.

Short chains of nucleic acid monomers.

A nucleic acid containing a couple of nucleotides, but not enough to call it a polynucleotide.

A short sequence of nucleotides linked together.

a molecule made up of a small number of nucleotides, typically fewer than 25. These are frequently used as DNA synthesis primers. [Source: NHBLI/NCBI Glossary

An artificially synthesized single stranded nucleic acid molecule used for a variety of exploratory uses.

A short, synthetically made stretch of single-stranded DNA.

Sequence of nucleic acids used as a probe in DNA based tissue typing.

(oligo) A short (2 - 50 nucleotides) sequence of (usually single-stranded) DNA which has been chemically synthesized for a specific experimental purpose.

A short segment of synthetic DNA.

A short segment of DNA or RNA.

a short sequence of nucleotides joined together

A small chain of nucleic acids.

Linear sequence consisting of a small number (no more than 20) of nucleotides.

Short sequences of nucleotides that are used as primers for the PCR.

Polymer made up of a few (2-20) nucleotides.

A short stretch of nucleotides, 2 to 200 nucloetides long.

Oligonucleotides are short sequences of nucleotides (RNA or DNA), typically with twenty or fewer bases. Automated synthesizers allow the synthesis of oligonucleotides up to 160 to 200 bases. The length of a synthesized base is usually denoted by 'mer', for example a fragment of 25 bases would be called a 25-mer.
