A bacterial cell that lacked the Rho protein would be a. resistant to several antibiotics. b. unable to terminate transcription of some genes. c. unable to carry out the elongation phase of transcription. d. unable to initiate transcription of some gene

b. unable to terminate transcription of some genes.

Explanation:

Rho protein is a polypeptide with 419 residues and is found in prokaryotic cells such as bacteria.

Termination refers to the point where a signal is made for transcription to stop. This usually occurs when a part of the DNA known as the terminator is transcribed. The transcription of this part halts then transcription process.

A lack of the rho protein means transcription of some genes won’t be able to be stopped( terminated).

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
