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 protein measured in the cells was likely synthesized by
A) mitochondria.
B) the nucleolus.
C) the smooth endoplasmic reticulum.
D) ribosomes.
