1. Which statement about site-directed in vitro mutagenesis is false? A. Point mutations can be created by making the change in 1 of the primers and having the primers (facing away from each other) extend around the whole plasmid.

B. Deletions can be created by having the 5' ends of the primers separated by the region you want deleted, therefore it won't be amplified during PCR.

C. Insertions can't be made because you can't add extra DNA to the primers used to amplify the plasmid.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
