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. Similarly, titration of the polynucleotide with a strong base causes duplex‐to‐single In comparing poly(dA) · 2poly(dT) with either the poly(dA) · poly(dT) · poly(dU) or the poly(dA) · 2poly(dU) triplexes, the substitution of thymine for uracil in the third strand results in an enhancement of stability against the 3 → 2 dissociation of ΔΔG° = −135 ± 85 cal (mol A) −1 at 37°C.

We show here that these protected sequences include tracts of poly(dG-dT).poly(dA-dC). We also report that these sequences are localized in regions flanking the rRNA transcription unit.

Present in DNA preparations isolated from crab species. Synthetic preparations have … the poly(dA:dT)-rich DNA we use here differs from the phased A-tracts that have been extensively characterized in the context of DNA looping, both in vivo and in vitro [36–44]. Phased A-tracts contain short poly(dA:dT) tracts spaced by non-A-tract DNAs such that the poly(dA:dT) tracts are in phase with the helical period of the DNA, generating globally curved structures that are known to Poly A-U Poly dA-dT Polydeoxyribonucleotides Poly A Poly(ADP-ribose) Polymerases Poly C Poly U Poly I-C Dopamine Poly(A)-Binding Proteins Poly G Poly Adenosine Diphosphate Ribose Poly T Poly I Molecular Sequence Data Dopamine Antagonists Polyribonucleotides Base Sequence 3,4-Dihydroxyphenylacetic Acid Poly(A)-Binding Protein I Dopamine Plasma Membrane Transport Proteins … What does POLY(DA)-POLY(DT) stand for?

The CD spectra of [poly(dA‐dT)] 2 and of poly(dA):poly(dT) are calculated for various DNA structures using the matrix method. The calculated and experimental spectra agree reasonably well for [poly(dA‐dT)] 2 but less well for poly (dA):poly (dT). The calculated CD spectrum of … Sigma activity in extracts of vegetative and sporulating B. subtilis Ammonium sulfate enzyme was prepared from vegetative and sporulating B. subtilis as described in Methods and assayed for a activity by measuring the transcription of phage fe DNA and poly(dA-dT) in vitro. Since the transcription of the EXPERIMENTAL SECTION Salmon DNA, poly(A) poly(U), poly(dA) poly(dT), and poly[d(A-T)J'poly[d(A-T)] were obtained from Sigma. against 2 mM NaCl and 2 mM HEPES buffer (pH 7.8) at 2+4 C. Experiments were conducted at 1.2 C in low-temperature room thermostated at 4 0C. Such temperature was chosen because of two reasons. Poly(dA:dT) sequences are fragile because long single-strand poly(dA) stretches at the replication fork are unprotected by the replication protein A (RPA).

Similarly, titration of the polynucleotide with a strong base causes duplex‐to‐single "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. Title: Sigma Shield DT Polyart.pdf Author: Aaddington Created Date: 11/27/2019 11:00:55 AM For poly- (dA)·poly (dT) we find ∆V = +97 mL/mol of bound netropsin at pH 7.0 and 10 mM sodium phosphate buffer. For poly [d (AT)]·poly [d (AT)] we find ∆V = −16 mL/mol of bound netrospin. This striking differential effect suggests that the poly (dA)·poly (dT) duplex compresses more water (or is more extensively hydrated). SIGMA Poly Products is a leading manufacturer and distributor of PE Fabrics, Multilayer Cross-Laminated Films, Tarpaulins, and Poultry Curtains in India.

We propose that the evolutionary expansion of poly(dA:dT) tracts in eukaryotic genomes promotes replication initiation, but at the cost of chromosome fragility. 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. The observation that poly(dA:dT) stimulates his3 tran-A Length of dA:dT(bp) 0 17 29 42 The reaction can be split under proper condition into two consecutive steps, the double helix formation of poly dA · poly dT and the addition of the poly U strand to form a trip · helix poly dA · poly dT · poly rU.

against 2 mM NaCl and 2 mM HEPES buffer (pH 7.8) at 2+4 C. Experiments were conducted at 1.2 C in low-temperature room thermostated at 4 0C. Transcription of poly(dA).poly(dT)-containing sequences was investigated in vitro using plasmids carrying a (dA) 34 ·(dT) 34 tract in the coding region of the lacZ gene.

Sigma factor, an essential component of the transcription machinery in E.coli , is released at the poly(dA-dT) tract once the transcription is initiated ( 13 ).

The efficiency of transcription of the (dT) 34 sequence on the transcribing strand by Escherichia coli RNA polymerase was substantially lower (∼60%) than that of the (dA) 34 Third, poly(dG:dC), a structurally dissimilar homopolymer that also affects nucleosomes, has transcriptional properties virtually identical to those of poly(dA:dT).
