Gene Expression Is One Response That Can Result from the Binding

Multiple Choice

Gene expression is one response that can result from the binding of a ligand to a cell receptor. How might the reception of such a signal travel from the receptor to produce such a cellular response?

A) By direct interaction of the cell receptor with the target DNA
B) The receptor produces a transcript that travels to the nucles
C) It is not known how signals travel from receptors to induce gene expression
D) Via a cascade of molecular events
E) Via electron excitation transfer
