Goldenrod gall flies lay their eggs in the goldenrod plant. the fly larvae cause the plant to form a gall, a swollen growth of plant tissue. large galls tend to be pecked open and their larvae eaten by birds. small galls are more frequently parasitized by tiny wasps, whose larvae eat the fly larva and take over the gall. this complex situation implies that is acting on gall size.

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?
