After reading the paragraph below, answer the questions that follow.
Much of the intracellular structure of a eukaryote cell is involved in protein synthesis. The accompanying figure shows the amounts of protein in cells at different parts of the cell cycle between two cell divisions. G
1 is a stage just after the cell has divided, and G
2 is the stage just before the cell divides again. S is a stage when the cell is synthesizing material such as DNA, mitochondria, and other organelles.
The technique used to produce the data displayed might be useful for a cancer biologist who wishes to
◦ determine whether a drug can prevent cell division.
◦ determine the effect of a drug on mitochondrial function.
◦ determine the effect of drugs on protein synthesis at various times in the cell cycle.
◦ determine the effect of a drug on microtubule assembly.
