Which of the following statements about signal transduction networks is incorrect?

ADifferent signaling pathways can synergistically regulate gene expression
BDifferent signaling pathways can antagonize each other's effects on gene expression regulation
CA single signaling pathway only regulates the activity of one transcription factor
DDifferent signaling pathways can activate the same transcription factor

Correct answer: C. A single signaling pathway only regulates the activity of one transcription factor

Signal transduction networks often involve multiple pathways that can either synergistically or antagonize each other to regulate gene expression. A single signaling pathway typically affects more than one transcription factor.
