Final answer:
Mitotic spindles start forming during prophase of mitosis, preparing the cell for chromosome alignment and separation in later stages.The correct option is:
A) Prophase
Step-by-step explanation:
Mitotic spindles begin to form during the prophase stage of mitosis. This process continues into prometaphase, where microtubules further assemble and attach to the kinetochores on the centromeres of sister chromatids.
During prophase, in both mitosis and meiosis, chromosomes condense, the nuclear membrane breaks down, and microtubules organize into a spindle apparatus, preparing the cell for the subsequent stages of cell division.The correct option is:
A) Prophase
