signs of distress at a temperature of 73 °F, and were certainly not capable of surviving at 158 °F. The organisms Dallinger had in his incubator at ...

Lambda phage
... gets duplicated with every cell division of the host. The DNA of the prophage that is expressed in that state codes for proteins that look out for
signs of stress in the host cell. Stress can be a result of starvation, poisons (like antibiotics), and other factors that can damage or destroy the host. ...
