Structure of Poly (I)•Poly (A)•Poly (I)

Journal of Biomolecular Structure and Dynamics, 2000
The molecular structure of poly (I).poly (A).poly (I) has been determined and refined using the continuous intensity data on layer lines in the x-ray diffraction pattern obtained from an oriented fiber of this polymorphic RNA complex. The polymer forms a 12-fold right-handed triple-helix of pitch 39.7A and each base-triplet is stabilized by quasi Crick-

Structure of Poly (U)•Poly (A)•Poly (U)

Journal of Biomolecular Structure and Dynamics, 2000
The molecular structure of poly (U).poly (A).poly (U) has been determined and refined using the continuous x-ray intensity data on layer lines in the diffraction pattern obtained from an oriented fiber of the RNA. The final R-value for the preferred structure is 0.24, far lower than that for the plausible alternatives.

Raman studies of nucleic acids. VII. Poly A · poly U and poly G · Poly C

Biopolymers, 1972
AbstractLaser‐excited Raman spectra of the double‐helical complexes poly A·poly U and poly G·poly C are reported for 2H2O and H2O solutions. The spectra are discussed in relation to their use as quantitative reference spectra for determining the dependence of the Raman scattering of RNA on secondary structure.

A poly I cryoform

Biosystems, 1967
Abstract During the investigation of the properties of fluorescent conjugates of polyriboinosinic acid (poly 1) we noted large irreproducibility in the polarization (25 °) values for a particular conjugate. In this report we show that the phenomenon is due to a stable, increased ordering of the secondary structure of poly I attained by brief exposure

American Poly

2023
Abstract This book provides a narrative of history of polyamory over the past century. It uses personal journals, underground newsletters, and other countercultural publications to trace the evolution of polyamorous thought and practice, setting it within the broader context of American culture.

Structure of Poly d(A)· Poly d(T)

Journal of Biomolecular Structure and Dynamics, 1992
On the basis of the x-ray data from polycrystalline and well oriented fibers of the sodium salt of poly d(A).poly d(T) (Arnott et al, Nucl. Acids Res. 11, 4141-4155 (1983), a revised B'-DNA model incorporating B-like adenine and thymine strands is shown to give a much better x-ray agreement (R = 0.25) than the previously assigned model consisting of ...
