Answer:
Ribosomes
Step-by-step explanation:
Ribosomes are the cell organelles involved in protein synthesis. During the process of translation they synthesize protein from mRNA. Ribosomes are made of two sub units, small and large. small sub unit reads the mRNA while large sub unit forms the polypeptide chain from amino acids. Each sub unit is further composed of rRNA and ribosomal proteins. They are slightly different in prokaryotes and eukaryotes as apparent by their different sedimentation rate during centrifuge process. This property is measured by Svedberg unit. Bacterial ribosome is 70s while eukaryotic ribosome is 80s.
