When the ribosome reaches a stop codon on the mRNA, no corresponding tRNA enters the A site. If the translation reaction were to be experimentally stopped at this point, which of the following would you be able to isolate?
a) an assembled ribosome with a polypeptide attached to the tRNA in the P site
b) separated ribosomal subunits, a polypeptide, and free tRNA
c) separated ribosomal subunits with a polypeptide attached to the tRNA
d) a cell with fewer ribosomes
e) an assembled ribosome with a separated polypeptide
