3. Meselson-Stahl & Scientific Reasoning Explain how the Meselson-Stahl experiment was able to eliminate both the conservative and dispersive models of DNA replication. In your answer, discuss the predictions each model would have made after one and two rounds of replication, how these differ from the observed results, and why semi-conservative replication remains the only viable model.

x 8.1: Maybe They’re Just Not That Into You You have a crush on someone. You know they will be at one of two parties, A or B. You like the music at party A better than the one at party B. However: they may or may not be into you to. If they are, then they too hope to show up to the same party as you. If they’re not, then they hope to show up to the opposite party. Oh, also: their taste in music is the opposite of yours. We’ll model this as a Bayesian game. In the first period “Nature” chooses whether your crush likes you back or not, each with probability 1/2. Then player your crush (player 2) observes nature’s choice, while you do not. Finally, you each decide which party to go to. Payoffs are as follows: (Into You) A B (Not) A B A 2,1 0,0 A 2,0 0,2 B 0,0 1,2 B 0,1 1,0 (a) What are the strategy spaces of the two players? (b) Draw the Bayesian normal form representation of this game. (c) Find all the pure strategy Bayesian Nash equilibria of this game.

Answer: Given: Diameter of the spot on the microchip = 5000 nm 1 nm = 10^3 pm To find the diameter of the spot on the microchip in picometers (pm), we can use the following conversion: 5000 nm * (10^3 pm / 1 nm) = 5000 * 10^3 pm = 5,000,000 pm Therefore, the diameter of the spot on the microchip in picometers is 5,000,000 pm.
