Match each phase of transcription with its correct description and key components.
Initiation ↔️ RNA polymerase binds to the promoter region on DNA; RNA polymerase, promoter
Elongation ↔️ RNA polymerase synthesizes the mRNA strand by adding nucleotides; RNA polymerase, DNA, nucleotides
Termination ↔️ mRNA transcript is released; polymerase detaches from DNA; Termination signal
