What Provides the Energy for Rho-Dependent Chain Termination

Question

What provides the energy for rho-dependent chain termination?
A) ATP hydrolysis distinct from any incorporation into the chain.
B) Nucleotide hydrolysis associated with incorporation into the chain.
C) Torsional stress built into the separating DNA strands.
D) There is no energy requirement.

Accepted Answer

Rho-dependent termination requires ATP hydrolysis by the Rho protein to provide energy for the termination process. This energy is distinct from any nucleotide incorporation into the chain.
