Here's why:
* Mitosis is a process of cell division that creates two identical daughter cells. It's essentially a copy machine for the cell's DNA.
* The DNA in the original cell is replicated before mitosis begins. This means there are two complete copies of the DNA, ensuring each daughter cell gets a full set.
* During mitosis, the replicated chromosomes are carefully separated and distributed equally to the two daughter cells. This process ensures that each daughter cell receives a complete set of genes, identical to the original cell.
Therefore, mitosis is a mechanism for producing genetically identical daughter cells. This is crucial for growth, repair, and maintaining the genetic integrity of an organism.
