Poly (A) and Poly (U) in Poliovirus Double Stranded RNA
Nature New Biology, 1973Poliovirus double stranded RNA (the “replicative form”) contains poly (A) at the 3′-end of the plus (genome-like) strand which is longer than poly (A) found in polio virion RNA. Digestion with 3′-exonuclease, hybridization to labelled poly (A) or poly (U) and affinity chromatography reveal that the minus strand contains 3′-terminal poly (U).

The formation of the triple helix of poly(A).poly(U).poly(U) was studied by using antibodies specific to poly(A).poly(U).poly(U). the 10-11 base chain length for oligo(A) and the 20-30 base chain length for oligo(U) may be the minimum sizes required to maintain a stable triple helix. Double-stranded poly(A).poly(U) which was the core of triple-stranded

AbstractWe prepared helices with noncomplementary bases by N1‐oxidation of poly A, followed by reaction with poly U. Mixing curves indicate that doubly and triply helical structures form, with only the unmodified adenines involved in base pair formation.

Suppression of hydrate and dimer formation in ultraviolet-irradiated poly (A + U) relative to poly U
Journal of Molecular Biology, 1966Abstract [ 32 P]Poly U and poly (A + U), containing a 1:1 mixture of poly A and [ 32 P]poly U, were irradiated at 280 mμ to study the influence of secondary structure on photoproduct formation in the uracil residues. Samples were removed as a function of exposure, hydrolyzed to completion with RNase, and chromatographed to give U, H ‡ , DU and DH ...

Radiolysis of Poly(U) in Oxygenated Solution
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1986Aqueous N2O/O2-saturated solutions of poly(U) were irradiated at 0 degrees C and the release of unaltered uracil determined. Immediately after irradiation G(uracil release) was 1.5 which increased to a value of 5.3 +/- 0.3 upon heating to 95 degrees C. Thereby all of the organic hydroperoxides (G = 6.8 +/- 0.7) and some of the hydrogen peroxide (G = 1 ...

A poly(U) polymerase in tobacco leaves
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1975A poly(U) polymerizing enzyme has been found in healthy and tobacco mosaic virus-infected tobacco leaves and has been partially purified by affinity chromatography on a gel prepared from agarose with chemically coupled RNA. The enzyme is stimulated by Mn-2+ and dependent on a polynucleotide, preferentially poly(A).

Poly(U) polymerase in rat brain
Nature, 1975MUCH interest has centred recently on the discoveries of ribohomopolymer sequences in RNAs of eukaryotic cells. Poly(A)1–3, poly(U)4 and poly(G)5 regions have been found in nuclear and cytoplasmic RNA fractions. These sequences are thought to have special implications for regulation of biological functions of RNAs.

Structure of the β-Form of Poly d(A) Poly d(U)
Journal of Biomolecular Structure and Dynamics, 1989The crystalline beta-form of the sodium salt of poly d(A).poly d(U) trapped in oriented fibers forms a Watson-Crick base-paired, 10(1) double-helix of pitch 3.2 nm. Two molecules are present in a monoclinic unit cell apparently isomorphous with beta-poly d(A).poly d(T). The two chains in each molecule both carry C2'-endo puckered furanose rings but are
