Question

Which transcription factors are normally bound to the Psf promoter in the presence of Mg2+ only?

(a) none
(b) MetA only
(c) MetA and Met B
(d) MetA, MetB, and MetC

Answer 1

None of the transcription factors are normally bound to the Psf promoter in the presence of Mg2+ only. Transcription factors play a crucial role in initiating and regulating gene transcription. However, in this specific case, the presence of Mg2+ alone does not attract any transcription factors to the Psf promoter.

Step-by-step explanation:

In the presence of Mg2+ only, none of the transcription factors are normally bound to the Psf promoter. Transcription factors play a crucial role in initiating and regulating gene transcription. However, in this specific case, the presence of Mg2+ alone does not attract any transcription factors to the Psf promoter.
