  oligomer \o*lig"o*mer\, n. (Chem.)
     A molecule composed of a small number of linked monomer
     units; a short polymer; -- compounds called oligomers have
     less than one hundred monomer units and usually less than
     thirty. Oligomers of increasing length are called {dimer},
     {trimer}, {tetramer}, {pentamer}, {hexamer}, {heptamer},


     {octamer}, {nonamer}, {decamer}, etc. In colloquial
     laboratory jargon, they may also be referred to as
     {nine-mer}, {ten-mer}, {eleven-mer}, {twelve-mer}, etc.,
     especially for oligomers of greater than eight units.

  octamer \oc"ta*mer\ ([o^]k"t[u^]*m[~e]r), n. [Octa- + Gr. me`ros
     part.] (Chem.)
     A molecule composed of eight monomer units bound to each
     other, usually in a linear array; as, an octamer formed from
     eight nucleotides is called an octanucleotide.

     Note: An example of an octapeptide might be represented using
           the standard abbreviations for the component amino
           acids, e.g.: met-ala-ser-glu-lys-ala-val-gly
           An octanucleotide might be represented using the
           standard single-letter abbreviations for the component
           mononucleotides, e.g.: ATGCATGC.
