What does POLY(DA)-POLY(DT) stand for? List of 1 POLY(DA)-POLY(DT) definition. Top POLY(DA)-POLY(DT) abbreviation meaning updated February 2021

Poly(dA.dT) sequences (T-tracts) are abundant genomic DNA elements with unusual properties in vitro and an established role in transcriptional regulation of yeast genes. In vitro T-tracts are rigid, contribute to DNA bending, affect assembly in nucleosomes and generate a characteristic pattern of CPDs (cyclobutane pyrimidine dimers) upon Search results for Poly dA-dT at Sigma-Aldrich.

Measurements of the steady‐state fluorescence spectrum and anisotropy, r, of the alternating polynucleotide poly(dA‐dT)‐poly(dA‐dT) were carried out in order to characterize its photophysical properties at room temperature. The shape of the fluorescence spectrum depends on the excitation wavelength, namely, the relative fluorescence

Up to 22% of the pyrimidines in the newly synthesized polymer were found by HPLC analysis to be 1 Nov 2000 Abstract.

We propose that the evolutionary expansion of poly(dA:dT) tracts in eukaryotic genomes promotes replication initiation, but at the cost of chromosome fragility. Poly(dA:dT) tracts: major determinants of nucleosome organization Eran Segal1 and Jonathan Widom2 Homopolymeric stretches of deoxyadenosine nucleotides (A’s) on one strand of double-stranded DNA, referred to as poly(dA:dT) tracts or A-tracts, are overabundant in eukaryotic genomes. They have unusual structural, dynamic, and "Poly dA-dT" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings). Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity.

Synthetic preparations have been used extensively in the study of DNA. Preparation of poly(dA:dT)/cationic lipid complex In order to facilitate the intracellular delivery of poly(dA:dT), poly(dA:dT) should be complexed with a cationic lipid transfection agent, such as LyoVec™ (see Related Products on the next page). A protocol for the preparation of a poly(dA:dT)/LyoVec™ complex is given below: 1. Aug 15, 2018 · Poly(dA:dT) tracts characterize strong DNA replication origins in mammals and cause replication-fork collapse and DNA breaks that underlie the expression of fragile sites. Feb 07, 2009 · Poly(dA:dT) tracts create larger nucleosome-depleted regions (a) Shown is a simple example focusing only on the immediate neighborhood of the boundary. All (five) possible nucleosome configurations are illustrated, in which a nucleosome (cyan ovals) can be placed within five basepairs of the boundary (blue triangle). Feb 01, 2009 · Homopolymeric stretches of deoxyadenosine nucleotides (A's) on one strand of double-stranded DNA, referred to as poly(dA:dT) tracts or A-tracts, are overabundant in eukaryotic genomes.
