The same signaling molecule that binds to the receptor on the outside of the cell is used to alter gene expression in the nucleus.

Question

Quizplus · Accepted Answer

The signaling molecule that binds to the receptor on the outside of the cell does not directly enter the nucleus to alter gene expression. Instead, it initiates a signal transduction pathway that eventually leads to changes in gene expression, often through the action of different molecules inside the cell.
