Which of the following happens during PROPHASE only? (Note: More than one correct answer)

• DNA condenses into chromosomes

• Sister chromatids are pulled apart

• Mitotic spindle starts to form

• Spindles attach to the kinetochore

• Nuclear membrane begins to disappear

Answer explanation

Spindles attach to kinetochore and nuclear membrane disappear during prometaphase
