NEET Biology question

Which of the following options gives the correct sequence of events during mitosis?

(A)Condensation → Nuclear membrane disassembly → Arrangement at equator → Centromere division → Segregation → TelophaseCorrect
(B)Condensation → Crossing over → Nuclear membrane disassembly → Segregation → Telophase
(C)Condensation → Arrangement at equator → Nuclear membrane disassembly → Centromere division → Segregation → Telophase
(D)Condensation → Nuclear membrane disassembly → Crossing over → Segregation → Telophase

Answer: (A)

Solution

The correct order of mitotic events is: chromatin condensation (prophase) → nuclear membrane disassembly (late prophase/prometaphase) → chromosome arrangement at the equatorial plate (metaphase) → centromere division (anaphase onset) → segregation of chromatids to opposite poles (anaphase) → telophase (decondensation,
