A biochemist isolates ribosomes from a human liver cell and determines the sedimentation coefficients of their two distinct subunits.
Q1. A biochemist isolates ribosomes from a human liver cell and determines the sedimentation coefficients of their two distinct subunits.
Answer: 40S and 60S
Explanation: Eukaryotic ribosomes consist of 40S and 60S subunits; 30S and 50S are tempting but are specific to prokaryotic cells.
