Unformatted text preview: L = 2) iv) 3 ligands are bound (N L = 3) v) 4 ligands are bound (N L = 4) Page 3 of 4 Name: b) (5points) Which states have the highest entropy? c) (5 points) Which states have the lowest entropy? d) (5 points) Which state will you find it in at equilibrium? e) (20 points) Let’s say that the binding constants are not equal, i.e., ligand L has a higher probability of being bound: p bound = 0.75 p unbound = 0.25 Plot the probability distribution for all of the states, p(i). Page 4 of 4 Name: 3.) DNA has 3 different possible configurations: A, B, and Z: A B Z Let the scores for each configuration e i be : e A = 1 , e B = 2, e Z = 3. a) (10 points) Write down the partition function, q. (you may substitute x = eb ) b) (10 points) Write down the expressions for p A and p B and p Z . c) (10 points) What is the variance of the distribution, <s 2 > , if all three configurations are equally possible?...
