For a protein to enter the endoplasmic reticulum as part of the endoplasmic
reticulum's lumen or part of the endoplasmic reticulum's membrane:
A. The messenger RNA goes directly to the ER.
B. A ribosome binds to the mRNA and a short stretch of protein is synthesized that
contains a signal sequence.
C. Ribosomes at the endoplasmic reticulum bind to the protein
D. Is a random event and one day the protein could go to the ER and on another day
, the same protein could associate with a free polyribosome.
E. None of the above.
