One difference between cancer cells and normal cells is that cancer cells:
Correct answer: D. Are always in the M phase of the cell cycle
- A. Are arrested at the S phase of the cell cycle
- B. Continue to divide even when they are tightly packed together
- C. Cannot function properly because they are affected by density dependent inhibition
- D. Are always in the M phase of the cell cycle
Explanation
Majority of cancer cells are always in the M phase of the cell cycle; they can be found in various phases depending on the specific characteristics of the tumor. However, certain aggressive or rapidly dividing cancer cells may exhibit a higher proportion of cells in the M phase due to their propensity for uncontrolled proliferation. This increased presence in the M phase contributes to the tumor's growth and aggressiveness, highlighting the dysregulation of cell cycle control mechanisms in cancer cells.

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.
