Question

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? Select all observations that accurately explain the effect of this mutation. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent All RNA molecules are longer than normal because the absence of functional rho means the transcription continues beyond the proper termination point Some RNA molecules would be longer than normal because these RNA came from the gene with rho-dependent terminator AIl RNA molecules are shorter than normal because the absence of functional rho would derail the transcription. Transcription does not take place because mutant rho would interfere with the RNA polymerase binding to the template

Explanation / Answer

Bacterial temperature sensitive mutation in gene encoding rho subunit-

Some RNA molecules would be longer than normal because the RNA came from the gene with rho dependent terminator.
