C. After various cycles of replication, the DNA was added to test tubes with a salt gradient and centrifuged at high speeds. This creates a density gradient that separates the DNA double helixes with different nitrogen isotopes. DNA that is all 1"N (light), a mix of 1“N and 15N, or all 15N (heavy) form three distinct bands in the test tube. Draw thick lines by indicated density to show the bands you would predict for each mechanism at 0, 1 and 2 cycles.
