Here's why:
* Mitosis is for growth and repair: Mitosis is the process by which a single cell divides into two identical daughter cells. This is essential for growth and development, as well as for replacing damaged or worn-out cells.
* Each daughter cell needs a full set of chromosomes: Each daughter cell needs to be a complete copy of the original cell, including all of its genetic material.
* Chromosomes are the carriers of genetic information: Chromosomes contain DNA, which holds the instructions for building and maintaining an organism.
* Duplication ensures equal distribution: By doubling the chromosomes before mitosis, the cell ensures that each daughter cell receives a full set of chromosomes. This is achieved through the process of DNA replication, which creates two identical copies of each chromosome.
In essence, chromosome duplication is a necessary step to ensure that each new cell inherits a complete set of genetic instructions, preserving the organism's genetic information.
