Molecular structure of the octamer d(G-G-C-C-G-G-C-C): modified A-DNA.
The deoxynucleotide fragment d(GpGpCpCpGpGpCpC) was synthesized and crystallized, and its three-dimensional structure was determined by x-ray diffraction techniques to a resolution of 2.25 A. The molecule forms a right-handed double helix in which the two base pairs at either end of the molecule are in the conventional A-DNA conformation, while the central four base pairs have a modified form i...

متن کامل(C; C\')-Controlled g-Fusion Frames in Hilbert Spaces
Controlled frames in Hilbert spaces have been recently introduced by P. Balazs and etc. for improving the numerical efficiency of interactive algorithms for inverting the frame operator. In this paper we develop a theory based on g-fusion frames on Hilbert spaces, which provides exactly the frameworks not only to model new frames on Hilbert spaces but also for deriving robust operators. In part...
متن کاملAn investigation into the solution structures of two self-complementary DNA oligomers, 5'-d(C-G-T-A-C-G) and 5'-d(A-C-G-C-G-C-G-T), by means of nuclear-Overhauser-enhancement measurements.
A 500 MHz 1H-n.m.r. study on two self-complementary alternating pyrimidine-purine oligodeoxyribonucleotides, 5'-d(C-G-T-A-C-G) and 5'-d(A-C-G-C-G-C-G-T), is presented. By using the proton-proton nuclear Overhauser effect virtually complete assignments are obtained and a large number of interproton distances [113 in the case of 5'-d(C-G-T-A-C-G) and 79 in the case of 5'-d(A-C-G-C-G-C-G-T)], both...
متن کاملAssociation of IL18 gene polymorphisms (positions -656 G/T, -137 G/C and +105A/C) with Kala-Azar
Background & Objective: Host resistance to Leishmania infection is mediated by cellular immune responses leading to macrophage activation and parasite killing. IL-18 known as interferon-γ inducing factor, stimulate IFN-γ production by T-cells. According to the important role of IL-18 in defense against VL and known effect of IL-18 gene polymorphisms on its production, the aim of this study was ...
