Question 1

Which of the following genotypes and conditions will have the lowest level of trp operon expression?
◦ trp+ / tryptophan present
◦ trpR- / tryptophan present
◦ trpL- / tryptophan present
◦ trp+ / tryptophan absent
◦ trpP- / tryptophan absent

Question 2

Which of the following is FALSE regarding how bacteria regulate the transcription of stress response genes?
◦ Under extreme growth conditions, such as heat stress and starvation, bacteria can induce transcription of alternative sigma factors.
◦ The rpoH gene encodes a sigma factor known as σ32 that is active at high temperatures.
◦ High heat can cause a change in the chaperone proteins.
◦ Transcription is activated by antitermination, which allows transcription to extend into heat shock genes.
◦ Holoenzymes containing an alternative sigma subunit are able to recognize the promoters of genes not transcribed by the common bacterial RNA polymerase.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
