Correct Answer
(1) polysomes
(2) polyribosomes
Explanation
Ribosomes can occur singly, attached to the endoplasmic reticulum, or in clumps called polysomes (also called polyribosomes). These clusters allow multiple ribosomes to translate the same messenger RNA simultaneously, increasing protein synthesis efficiency.
