Ecologic genomics of DNA: upstream bending in prokaryotic promoters.
After our analysis of the distribution of predicted intrinsic curvature along all available complete prokaryotic genomes, the genomes were divided into two groups. Curvature distribution in all prokaryotes of the first group indicated a substantial fraction of promoters characterized by intrinsic DNA curvature located within or upstream of the promoter region. We did not find this peculiar DNA ...
متن کاملTargeting CTCF to Control Virus Gene Expression: A Common Theme amongst Diverse DNA Viruses
All viruses target host cell factors for successful life cycle completion. Transcriptional control of DNA viruses by host cell factors is important in the temporal and spatial regulation of virus gene expression. Many of these factors are recruited to enhance virus gene expression and thereby increase virus production, but host cell factors can also restrict virus gene expression and productivi...
متن کاملCommon DNA structural features exhibited by eukaryotic ribosomal gene promoters.
Nucleotide sequences of DNA regions containing eukaryotic ribosomal promoters were analysed using strategies designed to reveal sequence-directed structural features. DNA curvature, duplex stability and pattern of twist angle variation were studied by computer modelling. Although ribosomal promoters are known to lack sequence homology (unless very closely related species are considered), invest...
متن کاملGenotyping common SNP and a microsatellite sequence closely linked to waxy gene in rice by DNA based markers
The potential of different DNA based molecular markers was examined for the detection of single nucleotide polymorphism (SNP) in the waxy gene and a microsatellite (SSR) sequence closely linked to it in a collection of rice varieties. DNA was extracted from leaf samples of 68 different rice cultivars by the CTAB method and specific primers were designed for the amplification of waxy gene and SS...
متن کاملA common sequence motif among prokaryotic DNA primases.
DNA polymerases cannot start a chain de novo and must rely on priming devices. In general, DNA primases provide free 3'-hydroxyl termini by the synthesis of short oligonucleotides that are base-paired with the template DNA (1). Bacteria, several bacteriophages and plasmids of certain incompatibility groups encode genes specifying DNA primases (2). Recently, two different sets of amino acid sequ...
