During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
