Quizplus · Accepted Answer

Sample II has the highest relative DNA content, suggesting it is in the G2 phase of the cell cycle when DNA is duplicated but has not yet undergone cell division. Sample I has a lower DNA content than Sample II, suggesting it may be in a different phase of the cell cycle or may represent a different cell type. Sample III has the lowest DNA content, suggesting it may be in a different phase of the cell cycle or may represent a different cell type with a lower amount of DNA.
