Eukaryotic Transcription Gene Regulation – Biology

In eukaryotic cells the structure of the chromatin complex of DNA is folded in a way that functionally mimics the supercoiled state characteristic of prokaryotic DNA, so although the enhancer DNA may be far from the gene in a linear way, it is spatially close to the promoter and gene. This allows it to interact with the general transcription factors and RNA polymerase II. The same mechanism hol… WebEnhancers are functional DNA elements that activate the transcription of a gene from a distance, independently of their positions and orientation with respect to the transcription start site. 51,52 Enhancers contain multiple binding sites for transcription factors that increase the promoter activity to promote MYC expression. 53 In addition to ... portable propane infrared utility heater
