Question

1. mitosis is the stage of cellular division where the nucleus divides. during which stage of mitosis do the spindle fibers attached to the chromosomes shorten and pull them apart towards opposite sides of the cell to ensure each new nucleus receives the correct number of chromosomes? telophase prophase metaphase anaphase

Explanation:

• In telophase, the nuclear envelope reforms and chromosomes de - condense.
• In prophase, chromosomes condense and the spindle apparatus begins to form, but the main action of pulling chromosomes apart does not occur here.
• In metaphase, chromosomes align at the equatorial plate.
• In anaphase, sister chromatids are pulled apart by shortening spindle fibers to opposite poles of the cell, ensuring each new nucleus gets the correct number of chromosomes.

Answer:

anaphase
