sigma factor उदाहरण वाक्य

उदाहरण वाक्य

2. In some bacterial species, such as " Clostridium botulinum ", this sigma factor may be necessary for sporulation.
3. The Gp67 protein of phage G1 has been found to interact with its host's RNA polymerase though an interaction with a sigma factor.
4. These studies have contributed much to our understanding of the regulation of gene expression, transcription factors, and the sigma factor subunits of RNA polymerase.
5. The LacUV5 promoter sequence conforms more closely to the consensus sequence recognized by bacterial sigma factors than the traditional " lac " promoter does.
6. The Gibbs phenomenon can be prevented by the use of ?-approximation, which uses the Lanczos sigma factors to help the sequence converge more smoothly.
7. The precise mechanism for changing the mRNA conformation is unknown . cspA protein binds Hfq, which upregulates production of sigma factors which mediate a stress response.
8. Similar to the sigma factors in prokaryotes, the general transcription factors ( GTFs ) are a set of factors in eukaryotes that are required for all transcription events.
