Fluorescently labeled circular DNA molecules for DNA topology and topoisomerases
DNA topology plays essential roles in several fundamental biological processes, such as DNA replication, recombination, and transcription. Typically agarose gel electrophoresis is employed to study DNA topology. Since gel electrophoresis is time-consuming and labor intensive, it is desirable to develop other methods, such as fluorescence-based methods, for such studies. In this paper we report ...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولFluorescence resonance energy transfer (FRET) sensors
The principle of "fluorescence resonance energy transfer" (FRET) has been exploited in cell biology to demonstrate the interaction of two proteins in living cells. FRET is highly specific and sensitive and allows for the online recording of events that modulate the interaction. We here demonstrate that FRET-based sensor molecules represent an alternative in monitoring receptor-dependent signall...
متن کاملDNA probes using fluorescence resonance energy transfer (FRET): designs and applications.
Fluorescence resonance energy transfer (FRET) is widely used in biomedical research as a reporter method. Oligonucleotides with a DNA backbone and one or several chromophore tags have found multiple applications as FRET probes. They are especially advantageous for the real-time monitoring of biochemical reactions and in vivo studies. This paper reviews the design and applications of various DNA...
