A fluorescent surrogate of thymidine in duplex DNA.
is a new fluorescent thymidine mimic composed of 2'-deoxyuridine fused to dimethylaniline. exhibits the same pKa and base pairing characteristics as native thymidine residues, and its fluorescence properties are highly sensitive to nucleobase ionization, base pairing and metal binding.

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Duplex DNA
This article describes the sequence-specific isolation and purification of intact double-stranded DNA (dsDNA) by oligonucleotide/PNA-assisted affinity capture (OPAC). The OPAC assay is based on selective tagging of a DNA duplex by biotinylated oligodeoxyribonucleotide (ODN) through formation of a so-called PD-loop. The PD-loop is assembled with the aid of a pair of PNA “openers”, which allow se...
متن کاملTemperature dependence of thermodynamic properties for DNA/DNA and RNA/DNA duplex formation.
A clear difference in the enthalpy changes derived from spectroscopic and calorimetric measurements has recently been shown. The exact interpretation of this deviation varied from study to study, but it was generally attributed to the non-two-state transition and heat capacity change. Although the temperature-dependent thermodynamics of the duplex formation was often implied, systemic and exten...
متن کاملEvaluation of Fluorescent Analogs of Deoxycytidine for Monitoring DNA Transitions from Duplex to Functional Structures
Topological variants of single-strand DNA (ssDNA) structures, referred to as "functional DNA," have been detected in regulatory regions of many genes and are thought to affect gene expression. Two fluorescent analogs of deoxycytidine, Pyrrolo-dC (PdC) and 1,3-diaza-2-oxophenoxazine (tC(°)), can be incorporated into DNA. Here, we describe spectroscopic studies of both analogs to determine fluore...
