Poly(A):poly(U) (polyadenylic acid:polyuridylic acid hybrid); poly(O8A):poly(U) (poly-8-oxy-adenylic acid:polyuridylic acid hybrid); poly(A):poly(MeNH5U) (polyadenylic acid-5-methylamino uridylic acid hybrid) and poly(O8A):poly(MeNH5U) (poly-8-oxyadenylic acid:poly-5-methylamino uridylic acid hybrid) were studied in chick embryos to compare the ...

A circular dichroism study of poly dG, poly dC, and poly dG:dC
Biopolymers, 1974AbstractWe have measured the ultraviolet circular dichroism spectra of oligo d(pG)5, poly dN AcG, poly dI, poly dC, two samples of poly dG, and four samples containing double‐stranded poly dG:dC. We find that oligo d(pG)5 and poly dG exist in self‐complexed forms as well as in single‐stranded forms. Unlike the self‐complexed form of poly dG, the single‐

Hole polarons in poly(G)-poly(C) and poly(A)-poly(T) DNA molecules
Science in China Series B: Chemistry, 2008The polaron might play an important role in the process of charge migration through duplex DNA stack. In the present work, we investigate properties of hole polarons in DNA molecules containing identical base pairs, such as poly(G)-poly(C) and poly(A)-poly(T), An extended tight-binding model (extended Su-Schrieffer-Heeger model), which involves the ...

Poly(organosilanes), Poly(carbosilanes), Poly(organosilazanes)
1996Attempts to completely replace the carbon in n-alkanes by the next element of group IV, silicon has been of special interest to practical as well as theoretical chemists ever since the work of Kipping [1]. Interest in the group of compounds, known as poly(organosilanes) 2b has not diminished to the present day, especially since it is a well known fact ...

Electrical Conduction through Poly(dA)-Poly(dT) and Poly(dG)-Poly(dC) DNA Molecules
Physical Review Letters, 2001We report direct measurements of electrical transport through poly(dA)-poly(dT) and poly(dG)-poly(dC) DNA molecules containing identical base pairs. The observed experimental results suggest that electrical transport through DNA molecules occurs by polaron hopping. We have also investigated the effect of gate voltage on the current-voltage curve.

Methylene blue intercalates with triplex poly(dT)*poly(dA)·poly(dT) but not duplex poly(dA)·poly(dT)
J. Chem. Soc., Chem. Commun., 1995Methylene blue intercalates with triplex poly(dT*dA·dT) even though it binds to the precursor duplex poly(dA·dT) in the major groove; the switch may be related to conformational modifications of the polynucleotide structure upon binding of the third strand.

Molecular Immunology, 1986
Eight monoclonal antibodies were prepared from a C57/black mouse which had been immunized with poly(rI).poly(dC). Two of the antibodies were specific for the RNA-DNA duplex but bound about 100-fold better to poly(rI).poly(dC) than to poly(rA).poly(dT). The other six antibodies were single-strand specific and bound to poly(rI) and in most cases to poly ...

Synthesis and coding properties of poly(c1A), poly(c3A), poly(c7A) and poly(h6A)
Biochemical and Biophysical Research Communications, 1973Abstract The homopolynucleotides poly(c1A), poly(c3A), poly(c7A) and poly(h6A) ++ were synthesized from their corresponding nucleoside diphosphates using polynucleotide phosphorylase. With the exception of poly(h6A), which displayed no hypochromicity, the homopolynucleotides showed melting profiles similar to poly(A). All these polynucleotides, poly(

Journal of Lesbian Studies, 1999
SUMMARY In contrast to the monogamous model for sexual relationships (including those of lesbians) in western society, friendships are permitted to be polyamorous. However, friendships do not receive the level of salience and priority that sexual relationships do. This article focuses on three issues that keep lesbians from prioritizing friendships: (1)
