The "restriction point" occurs here:
Correct answer: B. G1
- A. G0
- B. G1
- C. G2
- D. M
Explanation
The restriction point, also known as the G1 checkpoint, is a crucial control point in the cell cycle. It occurs late in the G1 phase, just before the cell commits to DNA synthesis (S phase), where the cell assesses external signals and internal conditions to decide whether to proceed with the cell cycle or enter a non-dividing state (G0 phase).

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
