Answer Key / Explanation : (a) -

(a)

In prokaryotes, ribosome attach to the 5’ end of RNA as soon as transcription begins. A bunch of ribosome moves along a single RNA molecule adding 15 amino acids/second to the polypeptide chain, almost the same speed at which RNA polymerase transcribes the RNA.
