Answer #1

Answer - (E) process of termination is not conserved

In prokaryotes Rho factor which is a specific protein that helps RNA polymerase to recognise the terminator site and terminate the transcription while in eukaryotes RNA polymerase enzyme recognise the Terminatore site and stop synthesis of RNA chain. In eukaryotes, the mechanisms for termination appear to differ for each of the three RNA polymerases. And eukaryotic RNA polymerase employs different terminaiton mechanism.
