Question
Explain the process of transcription in prokaryotes.
✓

Process of transcription in Prokaryotes are as follows DNA-dependent RNA polymerase that catalyses the process of transcription, three steps: initiation, elongation, and termination, Initiation: RNA polymerase binds to promoter, associated with initiation-factor (8) at 5' end of DNA, Elongation: nucleoside phosphates serve as substrate following the rule of complementarity, RNA polymerase help in opening the helix and continuous elongation, Termination: Terminator factor $(\rho)$, nascent RNA falls off along with RNA polymerase
