The story of the word

Chemistry needed a middle term once it became clear that short chains behave differently from long ones, and the same ὀλίγος that names rule by the few supplied it. There is no fixed boundary: a few units up to a few dozen, after which convention calls it a polymer. Short synthetic DNA strands are oligonucleotides, oligos in the lab, ordered by the tube.
