We propose that the evolutionary expansion of poly(dA:dT) tracts in eukaryotic genomes promotes replication initiation, but at the cost of chromosome fragility. (2006).

We demonstrate that poly(dA-dT) can adopt two conformations in solution, with the relative proportions dependent on the nature and concentration of the counter ion and cationic ligands. The synthetic DNA exhibits a dinucleotide repeat conformation on addition of CsF and Me4NCl at molar concentrations, with the NMR spectral changes reflecting a common conformational change at one glycosidic Abstract. The structure of poly(dA)ṁpoly(dT) currently arouses great interest, mainly because dA n ṁdT n stretches are associated with considerable DNA bending 1,2.Until recently the heteronomous DNA described by Arnott et al. 3, with the poly(dA) and poly(dT) chains in A and B conformations respectively, was the only detailed model of this structure.

Poly dA-dT Polydeoxyribonucleotides made up of deoxyadenine nucleotides and thymine nucleotides. Present in DNA preparations isolated from crab species. Synthetic preparations have been used extensively in the study of DNA. 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. Skip to main content 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.

In the human genome, Alu sequences appear approximately every 3 kb and 80% of them contain perfect A stretches of >10 bp ( 41). Although the biological and evolutional significance of these elements are not known, one of A list of lyrics, artists and songs that contain the term "poly da-dt" - from the Lyrics.com website. The minor-groove ligand netropsin provides a sensitive probe of the hydration difference between poly(dA)·poly(dT) and poly [d(AT)]·poly [d(AT)]. We have measured the volume change ∆V accompanying binding of netropsin to these polymers, using an improved magnetic suspension densimeter. 665433 Ensembl ENSG00000180573 ENSMUSG00000094248 UniProt Q93077 C0HKE2 B2RVF0 C0HKE1 C0HKE3 C0HKE4 C0HKE5 C0HKE6 C0HKE7 C0HKE8 C0HKE9 RefSeq (mRNA) NM_003512 NM_001177544 RefSeq (protein) NP_003503 NP_001171015.1 NP_783591.2 NP_835489.1 NP_835491.1 NP_835492.1 NP_835493.1 NP_835494.1 NP_835495.1 NP_835496.1 NP_835493 NP_835496 NP_835489 NP_835495 NP_835494 NP_835492 NP_835491 NP_783591 NP Jul 21, 2004 · CD and uv absorption data showed that high molecular weight poly(dA‐dT) · poly(dA‐dT), at 298 K, undergoes an acid‐induced transition from B‐double helix to random coil in NaCl solutions of different concentrations, ranging from 0.005 to 0.600M.

Poly(dA:dT) is a synthetic analog of B-DNA. Intracellular poly(dA:dT) is recognized by several cytosolic DNA sensors, such as ZBP1/DAI and LRRFIP1, triggering an immune response [1-5].

Synthetic preparations have been used extensively in the study of DNA. 1985), poly(dA:dT) tracts function in both orientations and longertracts are more stimulatory than shorter tracts. The stimulation of his3 transcription due to poly(dA:dT) ranges from a 3-fold increase for a 17 bptract to a 6-fold increase for a42 bp tract.

Apr 30, 2002 · As the 3′ poly(A) sequence becomes increasingly annealed by oligo(dT) primers, extension occurs only from the most 5′ annealed primer, and the resulting cDNAs contain shorter poly(dA/dT) sequences. We tested the dosage effect of the oligo(dT) primer on internal poly(A) priming. I purchased poly dA-dT.poly dA-dT 10 unit packs from sigma and the concentration was found spectrophotometrically. I got a weight of this product in ug/ ml but I would like to prepare a uM Historically, dT-conjugated cellulose was the primary resin for poly-dA purification, but its scarcity has prompted the development of alternative resins, most notably dT-functionalized magnetic beads. Nov 01, 2000 · 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 ChemicalBook provide Chemical industry users with Poly dA-dT Boiling point Melting point,Poly dA-dT Density MSDS Formula Use,If You also need to Poly dA-dT Other information,welcome to contact us.
