Enhancers can influence the transcription of genes far away on the same chromosome. How are the effects of enhancers restricted so that they do not exert inappropriate transcriptional activation of non-target genes?
Adi S.
Enhancers are sequences that affect the in itiation of the transcription of genes that are hundreds or thousands of nucleotides away. Transcriptional activator proteins that bind to enhancers usually interact directly with transcription factors at promoters by causing the interven ing DNA to loop out. An enhancer of bacteriophage T4 does not function by looping of the DNA (D. R. Herendeen et al. 1992. Science 256: $1298-1303$ ). Propose some additional mechanisms (other than DNA looping by which this enhancer might affect transcription at a gene thousands of nucleotides away.
Enhancers are __________. enhancers are __________. a form of bacterial promoter found in prokaryotic chromosomes inactive repressors that are unable to bind to dna sites in a dna molecule where rna polymerase binds to perform transcription specific dna sequences located distant to the promoter
