WebThis phenomenon, i.e. that a new function emerges that is similar to the constituting functions, is called self-similarity. The Gaussian is a self-similar function. Convolution with a Gaussian is a linear operation, so a convolution with a Gaussian kernel followed by a convolution with again a Gaussian kernel is equivalent to http://subtiwiki.uni-goettingen.de/wiki/index.php/Sigma_factors
WebNov 7, 2016 · Transcription is the first and most heavily regulated step in gene expression. Sigma (σ) factors are general transcription factors that reversibly bind RNA polymerase (RNAP) and mediate transcription of all genes in bacteria. σ Factors play 3 major roles in the RNA synthesis initiation process: they (i) target RNAP holoenzyme to specific promoters, … WebThe Sigma Factor: The sigma factor is involved in stable binding of the RNA polymerase to the promoter DNA; and possibly with transcription initiation. It is not involved in the transcription per se (i.e., RNA synthesis) as it is released when the RNA chain reaches 8-9 bases; the core enzyme then continues transcription.
