Which statement correctly describes a difference between prokaryotic and eukaryotic ribosomes?

Prokaryotic ribosomes are larger than eukaryotic ribosomes.

Svedberg units measure the weight of ribosomal subunits.

Eukaryotic ribosomes have a 60S large subunit, whereas prokaryotic ribosomes have a 50S large subunit.

Both prokaryotic and eukaryotic ribosomes function independently of mRNA.
