5. A mutant strain of Salmonella bacteria carries a mutation of the rho protein t hat has full activity at 37°C but is completely inactivated when the mutant strain is grown at 40°C. (Question # 21; Chapter 8-Genetics: An Integrated Approach). o Speculate about the kind of differences you would expect to see if you compared a broad spectrum of mRNAS from the mutant strain grown at 37°C and the same spectrum of mRNAs from the strain when grown at 40°C. Are all mRNAs affected by the rho protein mutation in the same way? Why or why not?
