Draw and label an anterior view of the human body with the thoracic and abdominopelvic cavities open with major organs drawn in. Hint: you will want to section the drawing sagittally and have the left (anatomical left) half of the cavities showing deeper organs only- ie on the left side show the kidney, ureter, spleen, pancreas, internal reproductive organs, bladder, etc and the right (anatomical) half showing the more superficial organs ie lungs, stomach, small intestine, large intestine, etch. These are only examples of organs, your drawing should be much more complete. Color code the organs by organ system.

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
