called prophase. During prophase, the nuclear membrane breaks down and the chromatin condenses into visible chromosomes. The centrosomes begin to move to opposite ends of the cell, and spindle fibers start to form.
There is Gap1 (G1 stage) where the cell is when it's not dividing. Then Synthesis (S stage) where the cell's DNA is duplicated. After that you have Gap 2 (G2 stage) where the cell gets ready to divide. Then the cell divides in mitosis. It ends with cytokinese where the cytoplasm splits and the plasma membrane disconnects.
metaphase I of meiosis
Through successive rounds of mitosis, replication of DNA in the S-phase of interphase results in shorter and shorter chromosomes. The structures called telomeres are attached to the ends of the chromosomes to prevent the chromosomes from becoming too short.
There are actually 5 steps of mitosis - Steps 1: the nucleus disappears and chromosomes start to appear. 2: the chromosomes make copies of themselves. 3:the chromosomes line up in the middle of the cell. 4:the chromosomes split and are pulled to both ends of the cell. 5:the cell splits.
In mitosis it is anaphase. In meiosis it is anaphase I and anaphase II.
Anaphase ends when the chromosomes stop moving.

metaphase I of meiosis
Two centrosomes are arranged at opposite poles of the cell are called prometaphase.
Telophase is marked by the arrival of the chromosomes at the poles. They will arrive at opposite ends of the poles.
Mitosis
The chromosomes pull apart and are pulled toward opposite ends of the cell during anaphase.
Through successive rounds of mitosis, replication of DNA in the S-phase of interphase results in shorter and shorter chromosomes. The structures called telomeres are attached to the ends of the chromosomes to prevent the chromosomes from becoming too short.
Two cells. Mitosis is when a cell splits, so it ends with two.
