Predict which signal would win out for the following combinations. A. Signals for import into the nucleus and import into the ER. B. Signals for export from the nucleus and import into the mitochondria. C. Signals for import into mitochondria and retention in the ER. Choose one (A, B, or C) and give a brief explaination.
