Which function does the cell membrane NOT perform?

The cell membrane is primarily involved in regulating what enters and exits the cell, thereby maintaining homeostasis, and facilitating communication with other cells. It also plays a crucial role in conducting electrical currents in specific cells, especially in muscle and nerve tissues, where ion channels in the cell membrane are vital for action potentials and muscle contraction.

However, storing genetic information is a function performed by the nucleus of the cell, which houses the cell's DNA. The cell membrane does not have a role in genetic storage; instead, its functions are more focused on protection, transport, and communication. Therefore, stating that the cell membrane stores genetic information is incorrect.
