Stages of transcription Match each event with the appropriate stage of transcription.The transcription bubble created by RNA polymerase moves along the DNA template.Once bound to the promoter, RNA polymerase begins to unwind the DNA The RNA-DNA hybrid within the transcription bubble dissociates. Reaching a terminator sequence causes formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed.RNA polymerase releases the DNA template. The RNA polymerase holoenzyme binds to the promoter. New nucleotides are added to the 3' end...

RNA polymerase releases the DNA template. Initiation Elongation Termination A process called clearance or escape. The RNA polymerase holoenzyme binds to the promoter A process called clearance or escape. Reaching a terminator sequence causos formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed. Once bound to the promoter, RNA polymerase begins to unwind the DNA. New nucleotides are added to the 3' end of the growing RNA transcript.
