The best response to describe how a liver cell and skin cell can have the same DNA sequence yet look different and perform different functions is:
The proteins are expressed differently in each cell.
This reflects the concept of gene expression, where different genes are turned on or off in different types of cells, leading to variations in the proteins produced and, consequently, differences in structure and function.
