You wish to engineer a protein so that it accumulates specifically in the endoplasmic reticulum, with limited accumulation elsewhere in the cell. To accomplish this goal, you need to design the gene so that... the protein contains a proline followed by series of amino acids with positively charged side chains. the protein contains the sequence Ser-Lys-Leu (SKL) on its C-terminus. the protein contains a signal peptide at the N-terminus and an ER-retention signal (KDEL) at the C- terminus. the protein contains a signal peptide at the N-terminus and a potential N-glycosylation site that can be modified to mannose-6-phosphate on the final protein. the protein contains a cleavable hydrophobic alpha-helix (signal peptide) at the N-terminus. 1 point An individual transport vesicle is... is endocytic if it is traveling toward the plasma membrane. recognized by its target membrane by the kind of coat protein it presents on its surface (e.g. clathrin). is exocytic if it is traveling toward the lysosome. recognized by its target membrane by the type of cargo in carries in its lumen..
