22. Which of the following statements about the effects of oxaliplatin on SW480 colon cancer cells, as observed in the DNA content histogram plots, is incorrect? 

(A) An increase in the sub-G1 population after oxaliplatin treatment indicates a rise in apoptotic cells due to DNA fragmentation.
(B) Oxaliplatin treatment leads to DNA damage in SW480 colon cancer cells.
(C) The accumulation of cells in the G2/M phase after oxaliplatin treatment suggests cell cycle arrest at this phase.
(D) Oxaliplatin treatment causes a majority of SW480 cells to pass through the G1 phase, indicating enhanced cell proliferation.
(E) Cells with a 4N DNA content cannot be distinctly separated into G2 and M phases due to their similar DNA content.
