What is the difference between a genes promoter and its enhancers?
The promoters are found in all genes that help in transcription which eventually will lead to produce proteins, the core promoter. This is a sequence of dna bases which are located upstream of about -35 bases( ie. the opposite direction of the transcription reation). They help in aid of the transcription to happen smoothly by having effective interaction with the transcription factors, thus forming a transcription complex and it also contains the RNA polymerase binding and regulatory sites necessary for transcription to happen. They usually have sequences called consensus sequence like TATA box in eukaryote or prinbow box in prokaryotes, which initiates the transcription by unwinding the DNA. Apart from the basal promoter, there are unique upstream promoter sequences which attract other sequence-specific transcription factors and help construct the transcription complex. Different genes are thus regulated by different promoters and combinations of transcription factors even though tran
