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

  • Condensation - nuclear membrane disassembly
    - crossing over - segregation - telophase

  • Condensation - nuclear membrane disassembly
    -arrangement at equator - centromere
    division - segregation - telophase

  • Condensation - crossing over - nuclear
    membrane disassembly - segregation -
    telophase

  • Condensation - arrangement at equator -
    centromere division - segregation -
    telophase

Answer

B.

Condensation - nuclear membrane disassembly
-arrangement at equator - centromere
division - segregation - telophase

The correct sequence of events during mitosis would
be as follows
(i) Condensation of DNA so that chromosomes become visible occurs during early to mid-prophase.
(ii) Nuclear membrane disassembly begins at late prophase or transition to metaphase.
(iii) Arrangement of chromosomes at equator occurs during metaphase, called congression.
(iv) Centromere division or splitting occurs during anaphase forming daughter chromosomes.
