Question

Is DNA the same in any or every cell in the human body? How do you know this?

Answer 1

All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein. For example, liver cells have different proteins than skin cells, even though their DNA is the same.
