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

Disciplinary Core Ideas: LS3.A Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species' characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function.
