Final answer:
In different types of human body cells, there can be differences in the DNA. Different cells have different genes turned on or off, resulting in variations in the DNA that is actively used in each cell.
Step-by-step explanation:
In different types of human body cells, there can be differences in the DNA. While all cells in the body have the same full set of DNA, not all of the genes are activated or expressed in every cell. This means that different types of cells will have different genes turned on or off, resulting in variations in the DNA that is actively used in each cell.
