Key Terms Definition:

Promotor: In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA.
Transcription is the process in which a gene's DNA sequence is copied to make an RNA molecule.
The elongation phase of transcription refers to the process through which nucleotides are added to the growing RNA chain.

Transcription occurs in the three steps—initiation, elongation, and termination

Step 1: Initiation. Initiation is the beginning of transcription. ...
Step 2: Elongation. Elongation is the addition of nucleotides to the mRNA strand. ...
Step 3: Termination.

The events occur at the promotor after binding of the basal transcription factors are follows:

After binding the correct order of events for transcription initiation is: A) closed complex formation, open complex formation, promoter clearance, start of RNA synthesis. B) closed complex formation, open complex formation, start of RNA synthesis, promoter clearance.

The events occur at the promotor before elongation can completely begin:

a.mrna is produced from nucleic acids.
b. the transcription process stops.
c. dna is produced from the mrna.
d. rna polymerase is guided to the correct place?
