Question

What happens during prophase of mitosis?

Answer 1

Mitosis:

1. Mitosis is the process of cell replication or reproduction in which one cell produces two genetically identical daughter cells.
2. In the context of the cell cycle, mitosis is part of the division process in which the DNA in the cell's nucleus is divided into two equal sets of chromosomes.
3. Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.

Prophase of Mitosis:

1. During the prophase stage, the chromosomes condense into an X-shaped structure.
2. Each chromosome is composed of two sister chromatids with the same information.
3. Chromosomes are paired, both copies of chromosome 1 are combined, and both copies of chromosome 2 are grouped together.
4. At the end of the prophase, the membrane surrounding the nucleus is destroyed and chromosomes are released.
5. The mitotic spindle extends across the cell between the centrioles as the centriole drifts towards the opposite pole of the cell.
