What happens in the patched-smoothened signaling system if the hedgehog is NOT present? A. In the absence of hedgehog , the cell-surface transmembrane protein called "Patched" represses transcription by degrading the "Smoothened" protein located on the cytoplasmic vesicle B. Hedgehog binds to the smoothened factor which inhibits and represses transcription by activating mutations C. The absence of the hedgehog protein induces transcription by allowing the patched portion to be silenced causing the smoothened protein to activate D. There is no relevance of the hedgehog, since transcription will occur regardless due to the presence of the Gli protein which acts as a transcription promoting factor.
