Co-translational inseion is seen with: (A) Translocon, (B) Chaperons, (C) Ubiquitin, (D) Mannose 6- P
Answer is A. The signal hypothesis states that protein is inseed into ER membrane at the same time its mRNA being translated on polyribosomes known as " co-translational inseion ". This is translocation endoplasmic reticulum. Components: N terminal signal peptide: Polyribosomes SRP SRP-R Sec 61 translocon TRAM TRAP proteins Reference: Harper; 30th edition
