A) ribosomes
B) rough endoplasmic reticulum
C) smooth endoplasmic reticulum
D) Golgi body
E) vesicles
Tertiary Structure
Refers to the three-dimensional shape that a protein assumes after it folds, contributing to its functional properties.
Polypeptide Chains
Long chains of amino acids linked by peptide bonds forming part of protein structure.

Final Answer :
B
Explanation :
Polypeptide chains are first synthesized on ribosomes and then transported to the rough endoplasmic reticulum (ER) where they take on their tertiary structure with the help of chaperone proteins. They may continue through the Golgi body and be modified further, but the initial assembly of polypeptide chains with other polypeptide chains occurs within the rough ER. Therefore, the best choice is B.
