Secondary structures of DNA.
نویسنده
چکیده
In view of the differences of the X-ray diffraction patterns for DNA fibers at 66 and 92 per cent relative humidities, it is proposed that the secondary structure of DNA consists of two partially intercalated double helices at 92 per cent. Possible biological implications are discussed.

SPECTROSCOPIC EVALUATION OF THE INTERACTION OF A TETRAZOLE DERIVATIVE SYNTHESIZED BY SEMI-GREEN METHOD WITH CALF THYMUS DNA AND BOVINE SERUM PROTEIN
Background & Aims: In recent decades, the application of tetrazole structures in various fields of medicine and industry has become very important, because they can cause structural and thus functional changes in the proteins. In this article, the effect of a new tetrazole derivative on calf thymus DNA (Ct-DNA) as well as on bovine serum albumin protein (BSA) in the solution was determined usin...
متن کاملPhysicochemical Position-Dependent Properties in the Protein Secondary Structures
Background: Establishing theories for designing arbitrary protein structures is complicated and depends on understanding the principles for protein folding, which is affected by applied features. Computer algorithms can reach high precision and stability in computationally designing enzymes and binders by applying informative features obtained from natural structures. Methods: In this study, a ...
متن کاملPhylogenetic Analysis of Beta-Glucanase Producing Actinomycetes Strain TBG-CH22 - A Comparison of Conventional and Molecular Morphometric Approach
Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...

متن کاملPrediction of Secondary Structure of Citrus Viroids Reported from Southern Iran
Abstract Viroids are smallest, single-stranded, circular, highly structured plant pathogenic RNAs that do not code for any protein. Viroids belong to two families, the Avsunviroidae and the Pospiviroidae. Members of the Pospiviroidae family adopt a rod-like secondary structure. In this study the most stable secondary structures of citrus viroid variants that reported from Fars province wer...
متن کاملNon-B DNA Secondary Structures and Their Resolution by RecQ Helicases
In addition to the canonical B-form structure first described by Watson and Crick, DNA can adopt a number of alternative structures. These non-B-form DNA secondary structures form spontaneously on tracts of repeat sequences that are abundant in genomes. In addition, structured forms of DNA with intrastrand pairing may arise on single-stranded DNA produced transiently during various cellular pro...
