NEET 2017 Biology question

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

(1)Condensation nuclear membrane disassembly crossing over segregation telophase
(2)Condensation nuclear membrane disassembly arrangement at equator centromere division segregation telophaseCorrect
(3)Condensation crossing over nuclear membrane disassembly segregation telophase
(4)Condensation arrangement at equator centromere division segregation telophase

Answer: (2)

Solution

In mitosis, chromosomes condense in prophase, the nuclear envelope breaks down at late prophase/prometaphase, chromosomes align at the equator (metaphase plate), the centromeres divide (start of anaphase) and the daughter chromatids segregate to opposite poles, and
