Which of the following does NOT apply to proteins synthesized on the rough endoplasmic reticulum?
A) Signal recognition particle
B) Vesicular transport
C) Signal sequence cleavage
D) Continuous translation
E) Docking protein

Question

Quizplus · Accepted Answer

Protein synthesis on the rough endoplasmic reticulum does involve continuous translation, so option D is the one that does not apply. A is correct because newly synthesized proteins have signal recognition particles that bind to their signal sequences, facilitating their transport to the RER. B is correct because vesicles mediate the transport of proteins from the RER to other organelles or the plasma membrane. C is correct because signal sequence cleavage occurs once the protein has been transported into the lumen of the RER. E is correct because docking proteins facilitate the binding of vesicles to their target membranes during vesicular transport.
