What are the two subunits of eukaryotic ribosomes?

Explanation:
Ribosomes in eukaryotes are built from two subunits that come together during translation: a large subunit and a small subunit. In eukaryotes these are 60S and 40S, which pair to form the 80S ribosome running in the cytoplasm and on the rough ER. The numbers reflect sedimentation rates, not exact sizes, and they help distinguish them from prokaryotic ribosomes, which are 70S made of 50S and 30S. So, the two subunits in eukaryotes are 60S and 40S.
