THE SIR2-SUM1 COMPLEX REPRESSES TRANSCRIPTION USING BOTH PROMOTER-SPECIFIC AND LONG-RANGE MECHANISMS TO REGULATE CELL IDENTITY AND SEXUAL CYCLE IN THE YEAST KLUYVEROMYCES LACTIS.

Deacetylases of the Sir2 family regulate lifespan and response to stress.We have examined the evolutionary history of Sir2 and Hst1, which arose by gene duplication in budding yeast and which participate in liftmaster header bracket distinct mechanisms of gene repression.In Saccharomyces cerevisiae, Sir2 interacts with the SIR complex to generate l

Listening comprehension is found to be among the most difficult tasks for the learners due to several reasons.Mostly, test-takers find difficulty in interpreting the intended meaning of the utterances in the TOEFL examination.To understand the intended meaning which is implied in and beyond the utterance itself, the afck benchmade test takers must

This article reports the numerical study of natural convection in a differentially heated cylindrical annular enclosure with a thin baffle attached to inner wall.The inner and outer walls of the annulus are respectively maintained at higher and lower temperatures, whereas the top and bottom walls are thermally insulated.Using an implicit finite dif

This study examines auroral colour camera data from the Canadian Dense Array Imaging SYstem (DAISY).The Dense Array consists of three imagers with different narrow (compared to all-sky view) field-of-view optics.The main scientific motivation arises from an earlier study by Knudsen et al.(2001) who used All-Sky Imager (ASI) combined with even earli
