Show transcribed image text Transcription of the structural genes in a repressible operon stops when the pathway's product is present starts when the pathway's product is present stops when the pathway's substrate is present starts when the pathway's substrate is present occurs all the time Indicate whether each of the following situations would increase or decrease transcription of the trp operon. A mutation that prevents the binding of the the ribosome to the 5' end A. decrease of the mRNA 5'UTR. increase Deletion in region 2 of the mRNA 5'UTR. Deletion in region 3 of the mRNA 5'UTR. Deletion of the string of adenine nucleotides that follows region 4 in the 5' UTR. Addition of tryptophan to the media. Deletion of the trpR gene.
