What is the role of the promoter in transcription?

It signals the start of transcription
It signals the end of transcription
It helps RNA polymerase bind to the DNA
It helps RNA polymerase move along the DNA

What is the role of the terminator in transcription?

It signals the start of transcription
It signals the end of transcription
It helps RNA polymerase bind to the DNA

Elongation
Initiation
Termination
Proofreading

What is the role of proofreading in transcription?

It helps RNA polymerase bind to the DNA
It helps RNA polymerase move along the DNA
It corrects errors in the RNA transcript
It helps RNA polymerase terminate transcription
