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

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

Correct answer · Option 2

\( Condensation \rightarrow nuclear membrane disassembly \rightarrow arrangement at equator \rightarrow centromere division \rightarrow segregation \rightarrow telophase \)

Explanation

In mitosis, chromosomes undergo condensation, nuclear membrane disassembles, chromosomes arrange at the equator, centromere divides, sister chromatids segregate, followed by telophase.
