During which stage of transcription do the following processes take place?
1. RNA polymerase binds to the promoter.
2. The RNA transcript is released.
3. The RNA transcript extended.
The RNA polymerase moves along the DNA in the 5' to the 3' direction.
The 3' end of the RNA molecule is produced first.
The RNA polymerase must first bind to a promoter sequence.
Transcription is always initiated at a "start codon".
