Question

During prophase each centrosome radiates out microtubules called :
(1) Mitotic apparatus
(2) Spindle apparatus
(3) Asters
(4) Spindle fibres​

Answer 1

During prophase, each centrosome radiates out microtubules called asters. (Option 3)

• Prophase is the initial stage of cell division.
• Two chromatids joined together by a centromere in the center is a chromosome.
• Chromosomes become visible during the prophase as the envelope around the nucleus disappears.
• It is the centrosome that supports cell division.
• A daughter and a mother centriole lying perpendicular to each other results in the formation of the centrosome.
• The microtubules that form around these centrioles are called asters.
• They help in positioning and organizing the chromosomes, motor proteins, and spindle fibers during cell division.
