Which structure is the primary site for the production of polypeptide chains?
A) Golgi body
B) ribosome
C) mitochondrion
D) lysosome
E) smooth endoplasmic reticulum
Polypeptide Chains
Long chains of amino acids linked by peptide bonds, which fold into specific three-dimensional shapes to form proteins.
Ribosome
A cellular organelle that functions as the site of protein synthesis, reading RNA sequences to assemble amino acids into proteins.
Golgi Body
Membrane-enclosed organelle that modifies proteins and lipids, then sorts the finished products into vesicles. Shaped like a stack of pancakes.

Final Answer :
B
Explanation :
Ribosomes are the primary site for the production of polypeptide chains. They are found either free in the cytoplasm or attached to the endoplasmic reticulum. The other organelles listed (Golgi body, mitochondrion, lysosome, and smooth endoplasmic reticulum) have functions related to processing, storage, and degradation of biomolecules, but not the production of polypeptide chains.
