(4pta) Draw the mechanism given the following reaction: 2. (4pta) (3pts) Rank the following in decreasing strength (1-strongest) of the C-halogen bond: 3. 4. Of all halogens we talked about in lecture, which halogen is considered the best leaving group? Explain why (give 2 reasons). (4pts) 5. Rank the following in decreasing nucleophile quality (1-strongest)?...

draw and label all relevang conformations. 2. Draw and label all relevant conformations (Newman projections) for 1-chior 2,2,2-tribromoethane. Also, identify the dihedral angle between pertinent substituents. Finally, draw a graph of relative energy vs. dihedral angle for 2,2,2-tribromoethane. (14 points) 3. Draw the most stable conformations for cis-1,4-dimethylcyclohexane and trans-1,4 dimethylcyclohexane and explain which geometric isomer is lower in energy. (12 points) 4. Using the CA-Cs bond axis as a reference, draw and label all relevant conformations (Newman projections) for...
Outline the extrinsic controls of the Renin-Angiotenson process. Include all pertinent steps to include what happens at the molecular, cellular, and gross anatomy levels. It is expected that your response will be comprehensive and contain all of the pertinent content reviewed in the text and lecture. Outline the extrinsic controls of the Renin-Angiotenson process.

4. Using the CA-Cs bond axis as a reference, draw and label all relevant conformations (Newman projections) for octane. Also, identify the dihedral angle between the pertinent substituents on C4 and C5. Finally, draw a graph of relative energy vs. dihedral angle for octane. (24 points)
tnpA res tnpR bla Tn3 Consider the complex transposon in the above illustration. Suppose you discover a derivative of this element that replicatively inserts into target DNA but then becomes "stuck" as part of a cointegrate. Your graduate student sequences the respective gene products and finds no change in the primary amino acid sequences of the encoded enzymes. In which locus must the defect lie? Choose one: A. res B. tnpA C. in one (or both) of the inverted repeats...
Suppose you take a Rubik's Cube and label all the edge squares with numbers as in the diagram. (It doesn't really matter what order you label them in, just so each square has a different number.) There should be 24 labeled squares in all (you can only see 12 of them in the diagram; the rest are on faces you can't see.) Then when you turn the various sides of the cube, you permute the set of numbers {1,2,...,24). We're...
