Termination mechanism
WebMechanism of Free Radical Polymerization. Free radical polymerization consists of three fundamental steps, initiation, propagation, and termination. Initiation, involves the formation of radicals followed by the radical's reaction with a vinyl monomer, propagation is ... The mechanism of termination is hypothesized to occur through a combination of direct promotion of dissociation through allosteric effects of hairpin binding interactions with the RNA polymerase and "competitive kinetics". The hairpin formation causes RNA polymerase stalling and destabilization, … See more In genetics, a transcription terminator is a section of nucleic acid sequence that marks the end of a gene or operon in genomic DNA during transcription. This sequence mediates transcriptional termination by … See more Two classes of transcription terminators, Rho-dependent and Rho-independent, have been identified throughout prokaryotic genomes. These widely distributed sequences are responsible for triggering the end of transcription upon normal completion of gene or See more • Terminator+Sequence at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more In eukaryotic transcription of mRNAs, terminator signals are recognized by protein factors that are associated with the See more • Termination codon • Termination factor • Terminator gene See more

http://www.polymerdatabase.com/polymer%20chemistry/radical%20mechanism.html WebUpstream intrinsic termination is used to regulate expression of many operons through mechanisms that alternatively permit or prevent transcription termination in a leader sequence or initially translated region (Figure 3).Alternative RNA structures (e.g., a Riboswitch or Ribosensor) in the nascent transcript dictate whether transcription …
Web29 Oct 2009 · We explain the evolution and termination of vertically aligned carbon nanotube (CNT) “forests” by a collective mechanism, which is verified by temporal measurements of forest mass and height, as well as quantitative spatial mapping of CNT alignment by synchrotron X-ray scattering. ... We propose that abrupt termination of CNT forest growth ... WebRho dependent termination is one of two types of termination in prokaryotic transcription, the other being intrinsic (or Rho-independent). RNA polymerase is able to terminate the transcription of some genes without assistance, for example at a series of several U residues following a hairpin; at other sites, however, it requires the ...

WebIn bacteria, two mechanisms for transcription termination have so far been documented, one mediated by a stem-loop structure formed in the nascent RNA transcript (intrinsic termination) and the other mediated by an ATP-dependent RNA translocase Rho (Rho-dependent termination). A third bacterial transcription termination model was recently ...
WebIn the present study, we have identified a novel mechanism for promoting prompt pre-BCR termination at the protein level. The BLNK-mediated pre-BCR signal induced the expression of LAPTM5, which in turn promoted the topological change of the intracellular pool of pre-BCR complexes, leading to their lysosomal degradation. geasnbcWeb2 Jun 2016 · Transcript termination is essential for accurate gene expression and the removal of RNA polymerase (RNAP) at the ends of transcription units. In bacteria, two mechanisms are responsible for proper transcript termination: intrinsic termination and Rho-dependent termination.
