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
A) determine whether a drug can prevent cell division.
B) determine the effect of a drug on microtubule assembly.
C) determine the effect of drugs on protein synthesis at various times in the cell cycle.
D) determine the effect of a drug on mitochondrial function.

Quizplus · Accepted Answer

The data displayed shows the amounts of protein in cells at different stages of the cell cycle, indicating the rate of protein synthesis at each stage. Therefore, the technique used could be useful for determining the effect of drugs on protein synthesis at various times in the cell cycle, which is a pathway commonly targeted in cancer treatment.
