polymer /poly·mer/ (pol´ĭ-mer) a compound, usually of high molecular weight, formed by the combination of simpler molecules (monomers); it may be formed without formation of any other product (addition p.) or with simultaneous elimination of water or other simple compound (condensation p.) .
Polymer A substance formed by joining smaller molecules. For example, plastic, acrylic, cellulose acetate, cellulose propionate, nylon, etc. Mentioned in: Eye Glasses and Contact Lenses polymer [pol′imər] Etymology: Gk, polys + meros, part a compound formed by combining or linking a number of monomers, or small molecules.

| Originally pili were thought to be homopolymeric structures composed of approximately 1,000 copies of a single structural subunit (fimbrin) packed in a helical array. Reading through homopolymers is important because it is estimated that a large fraction of the human genome is represented by stretches of nucleotide repeats referred to as homopolymeric regions. Sequencing of M13 was conducted on the entire genome, including so-called homopolymeric sequences. |
