* Ensuring each daughter cell receives a complete set of chromosomes: Mitosis aims to produce two genetically identical daughter cells. Each daughter cell needs a full set of chromosomes to function properly. Without chromosome duplication, the daughter cells would only receive half the genetic material, leading to dysfunction and likely death.
* Maintaining genetic stability: Duplication ensures that both daughter cells inherit the same genetic information as the parent cell. This is crucial for maintaining the organism's genetic integrity and preventing mutations from accumulating over generations.
* Providing template for segregation: The duplicated chromosomes act as templates for the separation of the genetic material during mitosis. The replicated chromosomes, joined together at the centromere, form sister chromatids. These sister chromatids are pulled apart by spindle fibers, ensuring each daughter cell receives a complete set of chromosomes.
In short, chromosome duplication in mitosis is necessary to ensure that each daughter cell receives a complete and identical copy of the parent cell's genetic material, maintaining genetic stability and ensuring proper cell function.
