6. Specific structural features tag proteins for transport tovarious intracellular and extracellular destinations. Severalexamples were described in chapter 12, including (1) the shortpeptide Lys-Asp-Glu-Leu, (2) characteristic hydrophobicmembrane-spanning domains, and (3) mannose-6-phosphate residuesattached to oligosaccharide side chains. For each structuralfeature, answer the following questions with detail:
a. Where in the cell is the tag incorporated into theprotein?
b. How does the tag ensure that the protein reaches itsdestination?
c. Where would the protein likely go if you were to remove thetag?
