Explanation:

The endoplasmic reticulum (ER) is an organelle in the cell. Its main function is to transport molecules around the cell. Controlling the cell's expression of DNA is mainly the function of the nucleus. Making DNA is also related to the nucleus and other processes. Since the ER is like a "transport" system in the cell (as hinted by the "transport" - related image of the truck with "ER" on it), it is responsible for transporting molecules.

Answer:

Transporting molecules around the cell
