Do all cells have the same DNA? Explain, please.

Sagot :

Nearly every cell in a person's body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
DNA is our genetic material, and if every cell in this world has the same exact DNA, we would be the exact same (unless something like nondisjunction occurs)
