She obtains two samples of diploid cells (2n), each with the same number of cells, and places sample 1 in a saline solution and sample 2 in a saline solution containing the newly discovered compound.

Explain how the compound most likely affected the cell’s progression through the cell cycle, and predict the relative number of cells found in each sample when the results were observed.
