Base-stacking and base-pairing contributions into thermal stability of the DNA double helix.

abstract：:Eukaryotic cells use numerous pathways to regulate RNA production, localization and stability. Several of these pathways are controlled by ribonucleases. The essential ribonuclease, Dis3, plays important roles in distinct RNA metabolic pathways. Despite much progress in understanding general characteristics of the Dis...

abstract：:We have developed a simple method to measure RNA synthesis in real time. In this technique, transcription reactions are performed in the presence of molecular beacons that possess a 2'-O-methylribonucleotide backbone. These probes become fluorescent as they hybridize to nascent RNA during the course of synthesis. We f...
