Biphasic Life Cycle—A Central Theme of Metazoan Evolution1

In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reprod… WebThis bacterium adopts a distinct biphasic life cycle consisting of a non-virulent replicative phase and a virulent transmissive phase in response to different environmental conditions; Hence, the timely and fine-tuned expression of growth and virulence factors in a life cycle-dependent manner is crucial for survival and replication. sonics transcription
