Becca and Ali are identical twins. They share the exact same set of genes. Becca and Ali have always lived in the same home and done
everything together. This year Becca and Ali are graduating high
school. Becca will attend college at Florida State University in the
sunny beach filled state of Florida. Ali will attend college at the
University of Maine in the cold snowy state of Maine. Your task is to
predict how these new environments might influence the twins in the
future. What kinds of changes might we see?

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?
