The hydrolytic step leading to the release of a polypeptide chain from a ribosome is catalysed by :

Nucleolus is formed from specific sites on chromosomes known as….

Assertion :- RNA polymerase associates with sigma -factor and rho -factor to terminant & initiate the transcription respectively. Reason: Association with these factors will not alter the specificality of the RNA polymerase.
