Answer:

  • Option B is true (Transcription factors are required for RNA polymerase ll-dependent transcription)

Explanation:

Option B is correct because many different transcription factors are involved in the eukaryotic transcription, particularly genes transcribe by RNA polymerase II. TFIID, A, B, F, E, and H are general or basal transcription factors of human.

Option A is wrong because RNA polymerase II first bind with the general transcription factor, TFIID. TFIID recognise the TATA box and forms a platform for TFIIB binding.

Option C is wrong because RNA polymerase II transcribe protein coding genes but it also transcribe small nuclear RNAs (snRNAs).

Option D is incorrect because transcription of poly-A tail is synthesized by template-independent RNA polymerase called poly(A) polymerase.

Option E is also incorrect- rho factor or rho-dependent termination is used by bacterial transcription termination process.
