Question

Using genetic engineering techniques, you have created a set ofproteins that contain two (and only two) conflicting signalsequences that specify different compartments. Predict which signalwould win out for the following combinations, meaning if theprotein has two conflicting sorting signals, where would theprotein end up? Explain your reasoning.

A. Signal sequence for import into the chloroplast and signalsequence for import into the ER

B. Signal sequence for export from the nucleus and signalsequence for import into the mitochondria

C. Signal sequence for import into nucleus and signal sequencefor retention in the ER
