polynucleotiden.

Brit.

/ˌpɒlɪˈnjuːklɪətʌɪd/, U.S.

/ˌpɑliˈn(j)ukliəˌtaɪd/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: poly- comb. form, nucleotide n.

Etymology: < poly- comb. form + nucleotide n., after German Polynucleotid (Levene & Mandel 1908, in Berichte der Deutsch. Chem. Ges. 41 1906). Compare mononucleotide n.

Biochemistry.

A polymeric compound whose molecule is composed of a (usually large) number of nucleotides (as in nucleic acids).

ΚΠ

1911 Jrnl. Biol. Chem. 9 394 Yeast nucleic acid is a polynucleotide.

1938 Q. Rev. Biol. 13 143/1 Ribose is also found in a specialized polynucleotide of the mammalian pancreas.

1970 R. W. McGilvery Biochemistry iii. 23 A particular arrangement of three nucleotide units in the DNA polynucleotide specifies a particular amino acid.

2001 Proc. National Acad. Sci. U.S.A. 98 13764/1 The genetic code relating sequences of polypeptides and polynucleotides is degenerate because there are many more triplet codons than encoded amino acid residues.
