What initiation and termination factors are involved in...

What initiation and termination factors are involved in transcription in eukaryotes?

Options

  1. Aσ\sigma and ρ\rho, respectively
  2. Bα\alpha and β\beta, respectively
  3. Cβ\beta and γ\gamma, respectively
  4. Dα\alpha and σ\sigma, respectively

Correct answer

A. σ\sigma and ρ\rho, respectively

Step-by-step solution

This question is not correct because out of the given initiation and termination factors, none is involved in transcription in eukaryotes. Only option (1) gives initiation and termination factors which are involved in transcription. These factors ( σ\sigma and ρ)\rho) initiate and terminate transcription in prokaryotes (not in eukaryotes). Initiation and termination factors involved in transcription in eukaryotes are General Transcription Factors (TF IIA - TF II H) and Transcription Termination Factor-1 (TTF-1), respectively.
