Answer:
The short peptide Lys-Asp-Glu-Leu
Explanation:
The place in the cell where the tag is incorporated into the protein is "the short peptide Lys-Asp-Glu-Leu."
This is illustrated when the tag is incorporated into Endoplasmic Reticulum-specific proteins as a form of polypeptides, (a combination of multiple short peptide Lys-Asp-Glu-Leu) that are then synthesized by ribosomes attached to the rough Endoplasmic Reticulum.
Therefore, in this situation, the correct answer is "The short peptide Lys-Asp-Glu-Leu"
