Question

Which factor is important for termination of transcription?

Options

• α (alpha)

• σ (sigma)

• ρ (rho)

• γ (gamma)

Answer 1

ρ (rho)

Explanation:

There are two ways to stop transcription in prokaryotes: rho-dependent and rho-independent termination. One protein implicated in rho-dependent termination is the p (rho) factor. It binds to RNA and helps RNA polymerase dissociate from DNA. The remaining choices (α, σ, and γ) are either not engaged in termination or a component of polymerase.
