The centrioles begin to move apart in the Prophase.
Prophase
prophase
anaphase
The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
The centrioles and asters are visible in the mid-prophase stage of mitosis.
The centrioles produce microtubules called spindle fibers, which push the centrioles apart as they grow.
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.

It's the CENTRIOLES and their star-like radiating structures, called asters.This is Stage 1 in Mitosis:Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
Prophase
No they do not, centrioles are the only organelles in a cell which are not synthesised during the G1 phase. During the telophase of cell division the two pairs of centrioles in each of their own centrosomes break down. Whilst a new nuclear memebrane is forming around the chromosomes a new par of centrioles is synthesised. Therefore centrioles are made during the telophase of the mitotic phase. Centrioles then divide into two pairs during the Synthesis phase. Each pair of centrioles then move to opposite poles of the nucleus during prophase.
