In the Meselson-Stahl experiment, 15N-labeled cells were shifted to 14N medium, at what we can designate as generation 0.

a. For the semiconservative model of replication, what proportion of 15N-15N, 15N-14N, and 14N-14N would you expect to find after 1, 2, 3, 4, 6, and 8 replication cycles? Explain.

b. For the conservative model of replication, what proportion of 15N-15N, 15N-14N, and 14N-14N would you expect to find after 1, 2, 3, 4, 6, and 8 replication cycles? Explain.

Astudent completed a lab report. which correctly describes the difference between the "question" and "hypothesis' sections of her report? "question states what she is asking, and "hypothesis" states the result of her experiment "question" states what she is asking, and "hypothesis" states what she thinks the answer to that question is in 'if. then because" format. "question" describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. "question" describes what she is trying to find out, and "hypothesis" states any additional information or prior knowledge about the question
