The Meleson-stahl experiment had what % of heavy-heavy bands in the second generation?

[Hint: after generation zero they grew the bacteria in light nitrogen]

DNA Replication
You have a culture of human cells in a dish. You have been growing these cells in normal media, but now you decide to add a fluorescently labelled adenosine to the culture media. The doubling time of your plate is about 8 hours, and after 8 hours you want to know where the fluorescently labelled adenosine has been incorporated. Which of the following is correct?
DNA Replication - Meselson and Stahl Experiment
Two scientists named Meselson and Stahl performed an experiment with bacteria where they grew bacteria in 15N containing media. They then cultured these bacteria in 14N only containing media for two replication cycles. They extract DNA after each replication cycle and used a centrifuge to determine the density of the DNA. The results are shown below. If they were to perform this same experiment and collect after three replication cycles, what would the DNA density look like?
