Factors regulate the formation of mrna
WebThere are many known factors that affect whether a gene is transcribed. These include factors that alter the accessibility of chromatin (chromatin remodeling), and factors that more-or-less directly regulate transcription … WebAug 2, 2024 · First, regulation of circRNA biogenesis initiates from and is coupled with the transcription of circRNA-producing pre-mRNA by Pol II. Second, cis and trans regulatory factors can further influence the efficiency of back-splicing, which is catalyzed by spliceosomal machineries.
