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.
