    I am pretty sure that this is negative repressible. Below is an analogy/metaphor about prokaryotic gene regulation. Please label the type appropriately and then explain why that type of regulation matches with that analogy. Possible types of prokaryotic gene regulation: Positive Inducible, Positive Repressible, Negative Inducible or Negative Repressible Analogy: I am trying to make my lecture about transcription. This is working well because there is no one at home where I am recording my PowerPoint. However, Dr. Corn is...

    A particular gene (call it xyz) is, like the lac operon, regulated both by Negative and by Positive control. However, unlike the lac operon, xyz's Negative control system is repressible. We'll call the repressor signal "signal 1." The Positive control system of xyz, like that of lac, is inducible. We'll call the inducer "signal 2." I want you to sketch the xyz gene in the presence and absence of each signal, as follows, and then determine whether the xyz gene...
