Question

how does rough endoplasmic reticulum help in protein synthesis​

Answer 1

it has been designed in such a way

Answer 2

Explanation:

• Ribosomes are attached to the membrane of the ER, making it “rough.” ... The process of protein synthesis starts when mRNA moves from the nucleus to a ribosome on the surface of the RER. As the ribosome builds the amino acid chain, the chain is pushed into the cisternal space of the RER.
