Question

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

Answer 1

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)

Answer 2

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).
