Studies of the endomembrane system often involve the use of a protein that can emit a green fluorescence (glow). a researcher wants to make a video of cell behavior, so she initially tags the outer nuclear envelope of a cell with the fluorescent tag and records for several hours. later, she sees that the tag is part of a secretory vesicle.
the fluorescent tag likely became incorporated into which of the following organelles during the video?
a. endoplasmic reticulum.
b. ribosomes.
c. mitochondria.
d. peroxisomes.
