Question

DNA coils up

1} nucleus dissolves
2} centrioles move to opposite sides of the cell
3} centrioles produce spindle fibers
4} 2 spindle fibers attach to each chromosome at the centromere (1 from each side)

Answer 1

In mitosis, the mitotic spindle forms, the nuclear envelope dissolves, and chromosomes attach to the spindle to separate and elongate the cell.

Step-by-step explanation:

In mitosis, during prophase, a mitotic spindle forms from the centrosomes. The nuclear envelope dissolves, and chromosomes attach to the mitotic spindle, which separates the chromosomes and elongates the cell.
