What is the fate of the nuclear membrane immediately after prophase is complete?
A. Forms pores to allow movement of molecules in and out of the nucleus
B. Reassembles around the sister chromatids
C. Breaks down into small vesicles
D. Reforms at the poles of the cell
参考答案:
C
本题详细解析:
Choice C is correct because immediately after prophase is prometaphase, during which the nuclear membrane breaks down into small vesicles.
Choice A is incorrect because, during prophase, the nuclear membrane already has existing pores. Choice B is incorrect because the nuclear membrane only reassembles during telophase, which is the last stage of mitosis, and not immediately after prophase. Choice D is incorrect because the mitotic spindle forms between the poles of the cell immediately after prophase.
