How many step to complete mitosis?

Answer 1

A cell goes through 4 Major steps to fully complete Mitosis. The cell first goes through Interphase which is NOT a step in Mitosis. Interphase is when the DNA replicates.

The first step in Mitosis is Prophase. This is when the DNA condenses into chromosomes which are attached in the center by a centromere. The nuclear membrane disintegrates freeing the DNA into the cytoplasm. Spindle fibers also begin to form.

The second step is Metaphase. The chromosomes line up in the center of the cell and spindle fibers attach on either side of the centromere to centriols on either side of the cell.

The third phase in Anaphase. The spindle fibers pull the chromosomes apart, half to each side toward the centriols.

The fourth phase, Telephase, is when the cell divides into two daughter cells (half of the chromosomes to each). The nuclear membrane reforms around the chromosomes which then unwind. The splitting of the Cytoplasm is called Cytpkinesis.
