How big are the ribosomes of eukaryotic cells
Web3 de abr. de 2012 · However, prokaryotic and eukaryotic ribosomes differ from several features. Prokaryotic ribosomes are 70S particles composing of 30S and 50S subunits. On the other hand, eukaryotic ribosomes are 80S particles composing of 40S and 60S subunits. We can consider this as a key difference between prokaryotic and … WebEukaryotic ribosomes have two unequal subunits, designated small subunit (40S) and large subunit (60S) according to their sedimentation coefficients. Both subunits contain dozens of ribosomal proteins arranged on a scaffold composed of ribosomal RNA (rRNA). Prokaryotic ribosomes are known as 70S. Therefore, the correct answer is option C.
