Some transcription signals are located thousands of base pairs upstream of the gene they regulate. how does the distant signal initiate transcription? (2 points) activation of the transcription signal releases a secondary messenger that binds to the start codon and initiates transcription. long regions of dna can loop over to enable regulatory connections. the distance between the transcription signal and the gene allows for preprogrammed delays in the start of transcription. the region between the transcription signal and the gene is an exon that is spliced out following activation of the transcription signal.
