You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold
6. Mutations in the promoter that prevent binding of RNA polymerase
7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase

Please help and there is an attached image. Thank you.
A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter.
A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.

One of the first things you wish to do is determine how mammals, birds, and reptiles are related. Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees. Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.arrow_forward
