A scientist collects a single stomach cell from a mouse. She determines the sequence of subunits in the DNA molecules from that cell. In what other cells in the mouse will the same sequence of subunits be found?

In that one cell that was collected from the mouse's stomach, but not in any other cells
In all of the other stomach cells, but not in any other types of cells
In stomach cells and other cells in the digestive tract, but not in any other types of cells
In stomach cells, in other cells in the digestive tract, and in cells elsewhere in the body
