Detailed explanation-1: -Ribosomes are composed of two subunits, the large and the small subunit, both of which consist of ribosomal RNA (rRNA) molecules and a variable number of ribosomal proteins .
Detailed explanation-2: -Ribosomes contain two different subunits, both of which are required for translation. The small subunit (“40S” in eukaryotes) decodes the genetic message and the large subunit (“60S” in eukaryotes) catalyzes peptide bond formation.
Detailed explanation-3: -Ribosomes consist of two subunits that fit together (Figure 2) and work as one to translate the mRNA into a polypeptide chain during protein synthesis (Figure 1).
Detailed explanation-4: -Mechanistic questions about translation in eukaryotes that will require additional structural insights to be resolved are also presented. All ribosomes are composed of two subunits, both of which are built from RNA and protein (Figs.
Detailed explanation-5: -70s ribosome is made up of 50s and 30s, and its total is not 80s because sedimentation rate of a particular ribosome is not equal to the total of 50s and 30s subunits. The sedimentation rate is less than a total of two subunits.
