These acidic vesicles are termed as endosomes. WebHow do ribosomes get to the rough ER? Protein synthesis begins in the cytosol with a process known as translation, in which the protein is assembled from an RNA sequence. As the protein grows, if it contains a signal sequence at its amino-terminal end, it will become bound to a signal recognition particle, which carries the ribosome to the RER ...
