Describe the four phases of mitosis-?

Answer 1

There are five, but I will except prometaphase for simplicity.

Prophase: The chromosomes are condensing, the nuclear envelope is dissipating and the centosomes are headed for the poles of the cell.

Metaphase: The chromosomes are fully condensed and lining up on the metaphase plate ( the middle of the cell ) and the centrosomes are in position and microtubules are attaching themselves to the lined up chromosomes.

Anaphase: In this phase the cetrosomes's microtubules are pulling the sets of duplicated chromosomes to opposite poles of the cell. A long process.

Telophase: In this phase the sets of chromosomes are at opposite poles and the nuclear envelopes are reforming around the chromosomes. The spindle apparatus of the cetrosomes is dissolving. In animal cells cytokenesis is taking place and splitting the cell into two daughter cells. On plants a cell wall forms between the two daughter cells.

Simplified version.

Answer 2

Interphase where chromosomes are dispersed, the Prophase where chromatides remain attached to each other, the Metaphase where chromosomes congregate and the Anaphase where the two chromatides separates.

Answer 3

The four phases of mitosis are prophase, metaphase, anaphase, and telophase. During prophase, the chromatin condenses into chromosomes, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes line up at the equator of the cell. In anaphase, the sister chromatids separate and move towards opposite poles. Finally, in telophase, the nuclear envelope reforms, the chromosomes decondense, and cytokinesis occurs, resulting in two daughter cells.
