events in mitosis which ensure that the number of chromosomes in the daughter cells remain the same as that in the parent cell

Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell. It is an essential process for growth, development, and repair in multicellular organisms. Here are the steps that ensure the number of chromosomes in the daughter cells remain the same as that in the parent cell:

1. Interphase: This is the phase where the cell prepares for division by replicating its DNA. Each chromosome is replicated to produce two identical copies, known as sister chromatids, which are held together at a region called the centromere.

2. Prophase: The chromosomes condense and become visible under a microscope. The nuclear envelope breaks down and the mitotic spindle, a structure made of microtubules, begins to form.

3. Metaphase: The chromosomes align at the equator of the cell, also known as the metaphase plate. The spindle fibers attach to the centromeres of the sister chromatids.

4. Anaphase: The sister chromatids separate and are pulled towards opposite poles of the cell by the spindle fibers. This ensures that each new cell will receive one copy of each chromosome.

5. Telophase and Cytokinesis: The chromosomes reach the poles of the cell and begin to decondense. A new nuclear envelope forms around each set of chromosomes, creating two separate nuclei. The cell then divides into two, each with an identical set of chromosomes.

Through these steps, mitosis ensures that the number of chromosomes in the daughter cells remains the same as that in the parent cell.
