उत्तर
The spindle fibres start appearing from prophase stage of karyokinesis.
Explanation:
During prophase, which is the very first stage of karyokinesis (nuclear division), the cell initiates the breakdown of the nuclear envelope and begins condensing chromatin into distinct chromosomes. Simultaneously, the centrosomes move apart to opposite poles of the cell, and microtubules begin assembling to form the early spindle fibres.
