Here's why:
* Duplication: Before mitosis begins, the cell replicates its entire DNA, including all chromosomes. This results in two identical copies of each chromosome.
* Separation: During mitosis, these duplicated chromosomes are separated and distributed equally to the two daughter cells.
* Equal Distribution: Each daughter cell receives one copy of each chromosome, making them genetically identical to the parent cell and each other.
Therefore, mitosis is crucial for growth, development, and repair of multicellular organisms because it ensures that every new cell inherits a full set of genetic information.
