Shоwn belоw is pG14. Nоte the following genetic elements: At the top of the mаp is the origin of replicаtion of the ColE1 plаsmid. Note that the rna-II is expressed from the trp promoter. Note that the trp promoter is not followed by any trp protein coding sequences. Moving clockwise: From 1:00-3:00 is the gene coding for a typical type 5 secretion system (autotransporter) expressed by a promoter that is positively regulated by the Vibrio harveyi LuxR protein. The MCS is a multiple cloning site in the passenger domain of the protein. From 4:00-5:00 is the tet gene expressed by the lambda pR promoter. From 8:00-10:00 is the lambda phage CI gene expressed from the lac promoter. At 11:00 is an oriT (mob) site. There are no other promoters on this plasmid other than those indicated on the map. Assume that all genes have appropriate translation start and stop codons. The short bars crossing the circle represent typical factor-independent terminators that will prevent transcriptional read through between these different elements. The host E. coli strain is normal but it lacks the F plasmid and lambda phage. For purposes of this exam, this E. coli has the complete set of genes for the Vibrio fischeri quorum sensing system in the chromosome, including autoinducer production and LuxR. The following questions are based on pG14. Here is a clue to help work these questions. Start at the genetic element that is being asked about and then work your way through the rest of the plasmid looking for genes that are related to those. Don't try to take in the whole plasmid at once. If you believe that a gene/locus is involved with an answer, but you are not sure of its regulation, be sure to mention this to get partial credit.
