There is an enzyme that catalyzes the production of the pigment responsible for dark fur color in siamese cats and himalayan rabbits. this enzyme is thermolabile, meaning that it does not function at higher temperatures. rabbits raised at 5 c are all black. if raised at 20 c,

Defend or refute the argument that the government has too large a presence in the agriculture industry.

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?
