Which of the following is FALSE regarding how bacteria regulate the transcription of stress response genes?
A) High heat can cause a change in the chaperone proteins.
B) The rpoH gene encodes a sigma factor known as a32 that is active at high temperatures.
C) Holoenzymes containing an alternative sigma subunit are able to recognize the promoters of genes not transcribed by the common bacterial RNA polymerase.
D) Under extreme growth conditions, such as heat stress and starvation, bacteria can induce transcription of alternative sigma factors.
E) Transcription is activated by antitermination, which allows transcription to extend into heat shock genes.

Question

Quizplus · Accepted Answer

Antitermination is a mechanism that allows RNA polymerase to read through a termination signal, but it is not specifically used to activate transcription into heat shock genes. Heat shock genes are typically regulated through the action of alternative sigma factors that recognize specific promoter sequences under stress conditions, not through antitermination.
