All of the following statements about Lambda phage are true, EXCEPT:

In a lambda phage, lytic phase and lysogenic phase does not occur together.Primary event in the genetic switch between lysis and lysogeny is governed by the level of lambda encoded proteins required for the lytic pathway. If one set of lambda immediate early genes are transcribed, then the lytic pathway is ored. If a transcriptionally repressor protein encoded by lambda cl gene inhibits the transcription, lysogeny is ored.
