The genes for tranfer ribonucleic acid (tDNA) and 5S ribonucleic acid (5SDNA) were isolated from the total deoxyribonucleic acid (DNA) of Escherichia coli. The relatedness of tDNA and 5S from E. coli and other species of Enterobacteriaceae was determined by reassociation of the isolated genes labeled with 32PO4 to unlabeled, unfractionated DNA. Double-stranded DNA was separated from unreacted D...

Hydrated ionic liquids (ILs) have been identified as solvent media able to enhance the structural stability of deoxyribonucleic acid (DNA). In this work, we investigate molecular interaction between imidazolium-based ILs and DNA during its thermal unfolding pathway, by exploiting synchrotron-based UV Resonance Raman scattering (UVRR) experiments. This technique gives a selective focus on respon...

Under proper conditions, one infective center was obtained for 3 X 108 molecules of P22 phage deoxyribonucleic acid (DNA) when lysozyme-ethylenediaminetetraacetic acid spheroplasts of Escherichia coil were transfected in the presence of 25 /Ig of protamine sulfate per ml. A 3to 50-fold B-specific and K-specific E. coli restriction of the incoming P22 DNA was observed. When P22 DNA-infected E. c...

Chalcone-derived pyrimidine is a well-known heterocyclic compound that commonly present in ribonucleic acid (RNA) and deoxyribonucleic (DNA) bio-isosteres. Pyrimidine derivatives are effective both the electronic industry drug industries. This review highlights synthesis of pyrimidines, namely mono-pyrimidine, bis-pyrimidine, fused pyrimidine, symmetric, asymmetric via one-pot two-pot methods. ...

Abstract Background Obesity-related oxidation stress plays a key role in obesity complications; however, its relation to thyroid status is an area for further research. The study aimed assess function obese children and oxidative deoxyribonucleic acid (DNA) damage. Results Fifty 40 normal weight were included . Anthropometric measurement, lipid profile, function, anti-thyroglobulin antibody, pe...

Deoxyribonucleic Acid (DNA) computing has demonstrated great potential in data encryption due to its capability of parallel computation, minimal storage requirement, and unbreakable cryptography. Focusing on high-dimensional image for with DNA computing, we propose a novel hash encoding-based algorithm, which consists encoding module content-aware encrypting module. Inspired by the significant ...

In this paper, a diversity deoxyribonucleic acid (DNA) chaotic encryption strategy is proposed to enhance the physical layer security of filter bank multi-carrier/offset quadrature amplitude (FBMC/OQAM) system. After input original binary bit stream encrypted, it subjected FBMC/OQAM modulation. The process data dynamically controlled by sequences generated hybrid system composed improved-Logist...

Double diffusion in agarose was employed for the characterization of a soluble nucleoprotein antigen that gave precipitin reactions with sera from patients with systemic lupus erythematosus. The soluble antigen that was isolated from calf thymus nuclei was demonstrated by enzyme degradation and ultracentrifugation studies, and by immunologic analysis, to be a complex of deoxyribonucleic acid an...

Simian virus 40 deoxyribonucleic acid (DNA) became associated in an alkaline-stable form with the DNA of Chinese hamster embryo cells at 15 to 20 hr post-infection, at the time when cell DNA synthesis and T antigen were induced. The integration process was not inhibited by d-arabinosyl cytosine and was only partially inhibited by cycloheximide.
