A Strain Of Bacteria Possesses A Temperature-Sensitive Mutation

ion in the gene that encodes the rho subunit. At high temperature, rho is not functional. When these bacteria are raised at elevated temperatures, which of the following effects would you expect to see? a) Transcription does not take place b) All RNA molecules are shorter than normal c) All RNA molecules are longer than normal d) Some RNA molecules are longer than normal e) RNA is copied from both DNA strand Explain your reasoning for accepting or rejecting each of these five options.

3) A) Because the rho protein is only involved in transcription termination, it should not affect transcription initiation or elongation. B) Without the rho protein, transcription would continue longer, producing longer than normal RNA molecules. Therefore, you don't expect to see RNA molecules that are shorter than normal. C) Only RNA molecules produced from genes that use rho-dependent termination can be longer. Therefore, all RNA molecules will not be longer than normal. D) Correct. Some RNA molecules that have rho-dependent termination would be longer. E) No, because rho-protein has nothing to do with initiation of transcription. RNA would still be copied from a single strand.
