You want to be able to observe a cell during specific points in mitosis. You expose the cell to a drug that prevents sister chromatids from separating. At which step of the mitotic cycle have you arrested the cell?

MCQs on the cell and its structures, including molecular compounds, structural features, and organelles including the nucleus, cytoskeleton, and extracellular matrix. Particular emphasis on transport mechanisms and membrane trafficking, cellular signaling, the cell cycle including mitosis and meiosis, and gene expression.
