Molecular Basis of Inheritance

Which factor is important for the termination of transcription?

  1. A.α(\alpha (alpha)
  2. B.σ(\sigma (sigma)
  3. C.ρ(\rho (rho)✓
  4. D.γ(\gamma (gamma)

Solution

In prokaryotes the rho (ρ)(\rho) factor binds the growing RNA and terminates transcription; the sigma (σ)(\sigma) factor is needed for initiation.
