Question

The ‘S’ in 30S and 50S subunits of ribosome stands for __.

Answer 1

'Svedberg Units' represents the sedimentation coefficients of the ribosomal subunits. Sedimentation coefficient is the rate at which a molecule sediments or settles down in a solvent. Based on this, the ribosomal subunits have been categorised as 30S and 50S (in prokaryotes) and 40S and 60S (in eukaryotes).
