A strain of bacteria possesses a temperature‑sensitive mutation in the gene that encodes the rho subunit. At high temperatures, rho is not functional. When these bacteria are raised at elevated temperatures, what would you expect to observe? a. All RNA molecules are shorter than normal because the absence of functional rho would derail the transcription.
b. Transcription does not take place because mutant rho would interfere with the RNA polymerase binding to the template.
c. Some RNA molecules would be longer than normal because these RNA came from the gene with rho-dependent terminator.
d. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent.
e. All RNA molecules are longer than normal because the absence of functional rho means the transcription continues beyond the proper termination point.
