<prompt> What directs vesicles carrying proteins modified in the Golgi cisternae to their appropriate place in the cell?A sequence of amino acids within the proteinsA specific carbohydrate bound to the proteinsCoatomer or clathrin proteins coating the vesicleComplementary SNARE proteins on the vesicle and its target organelle  <response>: The question is asking about proteins involved in protein targeting. Once proteins have been assigned to appropriate vesicles, the vesicles themselves must be addressed so that they reach the correct cellular location. This is done using a specific SNARE protein. Coatomer proteins and clathrin are necessary to promote the nipping off of segments of the membrane to form vesicles but are not involved in specific targeting. Reference: Harper; 30th edition
