<h3>Mitosis</h3>
The constancy of the chromosome number from one cell generation to the next is maintained through <u>Mitosis.</u>
<h3>What is mitosis?</h3>
- A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase.
- The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
<h3>What is the mitotic process?</h3>
- A eukaryotic cell's nucleus divides in two during the process of mitosis, which is followed by the division of the parent cell into two daughter cells.
- The term "mitosis," which translates to "threads," refers to the chromosomes' appearance as threads when the cell gets ready to divide.
<h3>What is the phases of the mitosis?</h3>
- prophase
- prometaphase
- metaphase
- anaphase
- telophase, and cytokinesis.
<h3>What is the importance of mitosis?</h3>
