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

1. σ and ρ, respectively
2. σ and β, respectively
3. α and ρ, respectively
4. β and γ, respectively

Correct answer: σ and ρ, respectively

Solution

The correct pair is sigma (σ) for initiation and rho (ρ) for termination, which are the classic transcription factors in prokaryotes. Eukaryotes use different initiation and termination machinery, so this question is really testing the bacterial system.
