5. Here is another promoter region in E. coli. (Also in a larger format in the BlackBoard file) This one is between two genes. The gene whose start codon is underlined in red encodes an amino acid / proton symport. The gene whose start codon is underlined in blue encodes a protein used in glycolysis. The binding site for the CAP protein (with its cAMP cofactor) is indicated in green. A. Both of these genes are transcribed by  70, whose "best consensus" binding site is in your Lecture 14 slides. Each promoter’s -35 site is indicated with a box. Copy-paste the sequence to your answer paper. Find and put a red/blue box around each promoter’s -10 sequence. Which is the "poorer" promoter – the red or the blue? What are two consequences of a gene having a poor promoter?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
