Chromatin transcription: Clearing the gridlock
A factor has been purified that specifically facilitates RNA chain elongation in a chromatin context; the properties of this factor help to define the challenges that lie ahead in understanding how RNA polymerase manages to transcribe DNA that is packaged into chromatin.
متن کاملDNA microarrays, chromatin, transcription
The DNA microarray-based technique has been developed to semi-quantitatively measure the in vivo global chromatin condensation state at the resolution of a gene. Chromatin was fractionated due to the differential solubility of histone H1-containing and histone H1-free nucleosomes. A set of genes non-randomly distributed between histone H1-free (uncondensed or open) and histone H1-containing (co...
متن کاملGridlock Modeling with MATSim
Traffic gridlocks represent an extreme case of network impedance. In regions with increasing impedance due to higher loads, gridlocks are expected to become more frequent and thus more relevant; consequently, they cannot be neglected in transport models anymore. This paper starts the examination of MATSim’s capability to model gridlock events. Closing Milchbuck and Schöneichtunnel being an east...
متن کاملChromatin-remodeling and the initiation of transcription.
The nucleosome serves as a general gene repressor by the occlusion of regulatory and promoter DNA sequences. Repression is relieved by the SWI/SNF-RSC family of chromatin-remodeling complexes. Research reviewed here has revealed the essential features of the remodeling process.
متن کاملThe Role of Chromatin during Transcription
Chromatin structure imposes significant obstacles on all aspects of transcription that are mediated by RNA polymerase II. The dynamics of chromatin structure are tightly regulated through multiple mechanisms including histone modification, chromatin remodeling, histone variant incorporation, and histone eviction. In this Review, we highlight advances in our understanding of chromatin regulation...
