Question
Spindle apparatus is formed during which stage of mitosis?
Options
Prophase
Metaphase
Anaphase
Telophase
Solution
Metaphase
Explanation:
The spindle apparatus formation begins in the prophase of mitosis, not metaphase. In this phase, the mitotic spindle begins to assemble as microtubules extend from the centrosomes, which start moving to opposite cell poles. The spindle apparatus is essential for aligning and separating the chromosomes accurately during cell division.
When the cell reaches metaphase, it is fully formed and organized. At this stage, chromosomes align along the metaphase plate with the help of the spindle fibers attached to their centromeres, preparing for separation in the next phase, anaphase.
