Gene Regulation and the Order of the Operon - YouTube

WebActivators and Repressors. There are two different types of gene regulation: positive and negative. Activators (and sometimes inducers) instigate positive regulation, and repressors instigate negative regulation. When an activator or inducer binds to an operon, the transcription process either increases in rate or is allowed to continue. WebFunctional study revealed that restoration of miR-381 significantly inhibited the invasion, migration, and epithelial–mesenchymal transition (EMT) of CRC cells. Luciferase reporter assay validated that Twist1, an important EMT inducer, was a direct target of miR-381, and rescued Twist1 attenuated the function of miR-381 in CRC cells. A coactivator is a type of transcriptional coregulator that binds to an activator (a transcription factor) to increase the rate of transcription of a gene or set of genes. The activator contains a DNA binding domain that binds either to a DNA promoter site or a specific DNA regulatory sequence called an enhancer. Binding of the activator-coactivator complex increases the speed of transcription by recruitin… first state miniature show

Web3 apr. 2014 · RNA is transcribed from DNA using an RNA polymerase (RNAP). In bacteria this is done by a single enzyme; however, eukaryotes have muliple polymerases which are each responsible for a specific subset of RNAs. To gain this specificity, the eukaryotic RNAP can recognize and bind to specific promoter elements. http://elflab.icm.uu.se/lore/ref/NatureGen-2014-Hammar.pdf
