Answer» 1. In bacteria, m-RNA provides the encoded message for protein synthesis; t-RNA brings specific amino acid to the site of translation; r-RNA plays role in providing binding site to m-RNA and tRNA. 2. There is single DNA dependent-RNA polymerase that catalyses transcription of all 3 types of RNA in bacteria. 3. RNA polymerase binds to promoter and initiates transcription (initiation) and synthesizes RNA. |
