Review. Consider how one might label the 5'ends of DNA for a footprinting experiment where you visualize where on the DNA a transacting protein binds to the cis acting promoter sequence The 5 phosphate(s) at the S'ends a DNA can be removed using a phosphatase, like calf intestinal phosphatase (CIP), in vitro, leaving a 5-hydroxyl group at the end of DNA CIP has no impact on the phosphates along the backbone of the DNA, just the 5' end phosphate and...

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...

QUESTION 4 Consider a car driving along a road, which has a traction force and a drag force acting on it. We can model the car with the ODE v'(t) m where v(t) is the velocity of the car, F, is the traction force and k is a drag coefficient. Given m 1000, Fi = 10000e, k 0.5 and v(0) 0, 13.63 (a) Use Euler's Method to...

Explain how MPI could be used to speed up a sort a million (1,000,000) values. If you have 1000 processors available how fast would your solution be (big O notation). I do not need code for this -- an explanation of an algorithm and how it would work is sufficient.
