polyribo- Biochem.|pɒlɪraɪbəʊ|
[f. poly- + ribo-.]
Formative element used in the names of polymers of ribonucleotides, as polyˌriboadeˈnylic, polyribo-cytiˈdylic, polyribo-inoˈsinic, etc., acid; also ˌpolyriboˈnucleotide. Cf. polyribosome s.v. poly- 1.
1956Nature 11 Feb. 271/1 Some 10–20 per cent of the total polyribonucleotide content of the bacteria was extracted by this procedure. 1959Times 10 Nov. (Guinness Suppl.) p. ii/6 An important series of papers on the synthesis of polyribonucleotides which have an important function in cellular metabolism. 1961Steiner & Beers Polynucleotides i. 6 The equimolar complexes formed by polyriboadenylic acid with polyribouridylic acid and with polyriboinosinic acid appear to have doubly stranded helical structures. Ibid. viii. 263 Even less is known of the detailed fine structure of polyribocytidylic acid... All that can be said is that some helical structure is present. 1964G. H. Haggis et al. Introd. Molecular Biol. ix. 228 (caption) T = polyribothymidylic acid (a polyribonucleotide containing only the base thymine found in natural DNA but not in natural RNA). 1970New Scientist 15 Jan. 96/2 Poly I:C—a combination of polyriboinosinic and polyribocytidylic acids—would stimulate interferon production both in cell cultures and in animals. 1976Nature 15 Jan. 141/2 Antibodies to native DNA, double-stranded RNA, and various synthetic polyribonucleotides occur with great frequency in patients with systemic lupus erythematosus (SLE).
So also polyde(s)oxyribo- (see deoxy-), in names of polymers of deoxyribonucleotides, as ˌpolyde(s)oxyriboˈnucleotide.
1956Federation Proc. XV. 291/2 To define the chemical events in the development of a bacterial virus, we have explored the pathways of polydesoxyribonucleotide synthesis in normal and infected cells. 1961Steiner & Beers Polynucleotides i. 5 The primary structures of polydeoxyribonucleotides and polyribonucleotides are identical except for the absence of the hydroxyl group on C2′ of deoxyribose. 1976W. Guschlbauer Nucleic Acid Struct. vi. 86 Single-stranded polydeoxyribonucleotides are, as a rule, less stacked and structured than their ribo counterparts. |
