NO, DNA content decrease during mitosis
Explanation:
- Mitosis creates two genetically identical daughter cells that are genetically similar to each other and to the parent cell. A diploid cell has 2N chromosomes and 2X DNA content when it first forms.
- Because each chromosome has reproduced its DNA, the cells remain genetically diploid (2N chromosomal number) but have 4X DNA content.
- A connected pair of identical sister chromatids now makes up each chromosome. Sister chromatids split and go to opposing ends of the dividing cell during mitosis. Mitosis results in the formation of two identical cells, each with 2N chromosomes and 2X DNA.
