The correct response is: The proteins are expressed differently in each cell.
Even though liver cells and skin cells have the same DNA sequence, they can look and function differently due to the specific genes that are expressed in each cell type. Different patterns of gene expression lead to the production of different proteins, which ultimately determines the characteristics and functions of the cells.
