Transcription and RNA Processing

ID #2241

How does the molecule, Rho, have the ability to denature double-stranded nucleic acid? I thought that the helicase function of Rho was to separate RNA from DNA.

The Rho protein is an ATP-dependent helicase, and helicases need not denature only dsDNA. It can also melt the interaction between an RNA and a DNA or the secondary structure of RNA (which would be like the dsRNA that you find in a hairpin structure).
