Question

Microtubules, appearing around centriole pair in the beginning of prophase in animal cells form

• A. Spindle
• B. Aster
• C. Spindle pole
• D. Chromosome fibres

Answer 1

The correct option is B Aster

Asters initially appear in prophase. They form around each centriole pair. Asters organize spindle fibers that extend from the cell poles and fibers that attach to chromosomes at their kinetochores. This separation is accomplished as spindle fibers shorten, pulling attached chromatids along with them.
