Question

What are the phases of mitosis and what happens in each?

Answer 1

Explanation:

Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.

It includes the following phases -

1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .

2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and  Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .

3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .

4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.

5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.

6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.
