Explain why the prokaryotic ribosomal subunits are defined as 30S and 50S, but the assembled ribosome is defined as 70S.

Solutions

Expert Solution

The ribosomal subunits are indicates as 30S, 50S, etc. in which the S is the measure of rate of sedimentation in Svedberg units, but does not represent he size. Thus, we should not add the individual fragments to determine the ribosome size. Thus, in prokaryotes, the 30S and 50S ribosomes combine together to form the 70S ribosomes.

During initiation of translation: Question 6 options: both 70S and 30S ribosomal subunits must simultaneously recognize an mRNA to bind. the initiator tRNAmet binds to the A site of a ribosome. IF-3 must be recruited to the 30S ribosome in order for the 70S initiation complex to assemble. specific rRNA base pairs with a sequence in mRNA to position a ribosome at the start codon. there is no energy expenditure as the tRNA binding to mRNA is via complementary base...
