| homopolymer tailing | A lab technique where a nucleic acid homopolymer (a long chain of the same nucleotide over and over) is attached to the end of a piece of DNA as a part of DNA cloning. It is especially useful in cDNA cloning to get the cDNA inserted into the cloning vector -- a nucleic acid homopolymer which contains the complementary nucleotide to the cDNA tail is attached to the vector, which then pairs with the tail on the cDNA.

| chlorethene homopolymer | <chemical> Chloroethene homopolymer. A polyvinyl resin used extensively in the manufacture of plastics, including medical devices, tubing, and other packaging. It is also used as a rubber substitute. Residues are present in human body tissues. Chemical name: Ethene, chloro-, homopolymer (12 Dec 1998) |
| homopolymer | <chemistry> A type of polymer (large molecule which consists of a chain of similar smaller molecules called monomers) where all of the monomers are the same thing. For example: a polypeptide which consists entirely of the amino acid lysine linked end to end, instead of many different amino acids linked end to end, would be a homopolymer. (09 Oct 1997) |
