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

Question

Quizplus · Accepted Answer

The binding of a ligand to a cell receptor typically initiates a cascade of molecular events, often involving secondary messengers and various proteins, which eventually leads to changes in gene expression. This process allows the signal from the cell surface to be amplified and precisely regulated before affecting gene expression.
