Which of the following is not an accurate description of events leading to the lysogenic pathway following viral infection in a bacterium?
A. Upon infection, the linear bacteriophage DNA forms a circle and transcription is initiated at promoters PL and PR. The transcripts from PR encode the proteins cro and cII. B. Reduction in the concentration of cI protein is the most important contributor to lysogeny. C. Reduced protease activity due to poor conditions allows cII to accumulate, which then stimulates transcription from PE and thus expression of cI. D. cI protein binds to operator OR , preventing cro and cII expression. E. cI protein stimulates transcription from promoter PM, leading to even more cI production. The increased cI binds to operator OL and inhibits PL.
How could telomerase inhibitors be used to treat cancer? What will be an ideal response?
The Japanese puffer fish, a food delicacy, contains the chemical tetrodotoxin (TTX). If too much TTX is ingested, this
can prevent breathing because TTX:a. binds to and activates voltage-activated K+ channels. b. binds to and activates voltage-activated Na+ channels. c. blocks the passage of Ca+ through voltage-activated Ca+ channels. d. blocks the passage of Na+ through voltage-activated Na+ channels. e. blocks the passage of K+ through voltage-activated K+ channels.
