Q
what do transcription factors do?
A
Transcription factors regulate gene expression by binding to DNA, recruiting RNA polymerase, and either activating or repressing transcription.
2
Q
What is the function of the general transcription factors?
A
combine with RNA polymerase to form a preinitiation complex that is competent to initiate transcription as soon as nucleotides are available.
(bc the general job is to start the transcription)
3
Q
What is the promoter?
A
DNA sequence that acts as a transcription start site.
(it is promoting (advertising) transcription) (it promotes the transcription to the rna polymerase to convice it to start transcription)
4

A
It is the site where transcription stops.
