Cell Cycle and Cell Division: NEET questions with solutions
This chapter tests the phases of the cell cycle, the events of each stage of mitosis and meiosis, and chromosome and DNA counting through division. NEET marks are lost on confusing chromosome number with DNA content, on the sub-stages of prophase I, and on what separates in anaphase I versus anaphase II.
