Transcription factories
There is considerable evidence that transcription does not occur homogeneously or diffusely throughout the nucleus, but rather at a number of specialized, discrete sites termed transcription factories. The factories are composed of ~4-30 RNA polymerase molecules, and are associated with many other molecules involved in transcriptional activation and mRNA processing. Some data suggest that the p...
متن کاملB - Factories
The evolution of B-Factories is discussed, and comments are made about the common features of present-day asymmetric storage ring collider designs. * Work supported by Department of Energy contract DE-AC03-76SF00515. Presented at the 4th International Symposium on Heavy E’lavour Physics, Orsay, France, June 25-29, 1991 There was a symposium Progress on B-Factories the day before the Heavy Flavo...
متن کاملTranscription factories.
There is increasing evidence that different transcription units are transcribed together in discrete nuclear structures known as transcription factories. Various new techniques enable us to detect and characterize these structures. We review the latest findings and discuss how they support a model for transcription and chromosome organization.
متن کاملImprovement of Cement Properties Using a Single Multi-functional Polymer
Cementing of the casing pipes inside the wellbore is considered as one of the most expensive and difficult operations during the well construction process. A low quality cementing job leads to further repair operations, which are usually costly and time-consuming to conduct. Polymer cements are being used for decades in the oil and gas industry due to their improved properties such as sedimenta...
متن کاملMicrobial Cell Factories
In contrast to bioreactors the metabolites within the microbial cells are converted in an impure atmosphere, yet the productivity seems to be well regulated and not affected by changes in operation variables. These features are attributed to integral metabolic network within the microorganism. With the advent of neo-integrative proteomic approaches the understanding of integration of metabolic ...
