Under what condition would a temperate bacteriophage infecting Staphylococcus aureus (an aerobic bacteria commonly found on the human body) be shifted by environmental cues from lysogeny to a lytic cycle? Choose one: A. when phage-infected cells are incubated at 37°C B. when phage-infected cells are incubated at 50°C C. when phage-infected cells are placed on nutrient-rich media D. when phage-infected cells are incubated at atmospheric levels of oxygen

Answer is option "B"

Explanation:

High temperatures are not permissive for bacterial growth and lead to cellular stress, which would lead to a shift  from lysogeny  to the lytic phase  Bacteriophage infection has generally been contemplated utilizing bacterial hosts developing exponentially, with dynamic air circulation, in one of a couple of all-around examined media The resurgence of enthusiasm for restorative, prophylactic, and agrarian phage applications, just as developing consciousness of the significant ecological effect of phages, make it progressively imperative to contemplate the subtleties of phage-have connections under conditions that are increasingly like those experienced in indigenous habitats Hence, the right answer is option "B"

C) to ensure each new cell has an exact copy of the dna
