Question

What are the major functions of "Asters of centrosome"?

Answer 1

Asters (Latin word for stars) of centrosomes are microtubules and are formed around centrosomes during mitosis. During prophase, asters and centrosomes move to the opposite sides of the cell. During metaphase, asters extend and connect to the centromere of chromosomes. During anaphase, those microtubules pull the chromatids apart to the centromeres on the opposite sides of the cell.

Simply speaking, it helps the centrioles to move apart in early stages of division.
