Here's why:
* Lysogenic: This term refers to the phage's ability to integrate its DNA into the host's genome and remain dormant (latent) for a period of time.
* Temperate: This term describes the phage's ability to exist in both a lytic and lysogenic cycle. It can choose to reproduce actively (lytic cycle) or integrate into the host's genome (lysogenic cycle).
Therefore, "lysogenic phage" and "temperate phage" are essentially interchangeable terms.
