3. Nuclear membrane and nucleolus disappear.

4. Chromosomes are already duplicated as paired chromosomes and chromatids attach to each at a small region called centromere.

Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.
