<Ol> <Li> Immediate early genes: These genes are expressed from promoters recognized by the host RNA polymerase, and include Cro, cII, and N. CII is a transcription factor that stimulates expression of the main lysogenic repressor gene, cI, whereas Cro is a repressor for cI expression . The lysis - lysogeny decision is mainly influenced by the competition between Cro and CII, resulting in the determination of whether or not sufficient CI repressor is made . If so, CI represses the early promoters and the infection is shunted into the lysogenic pathway . N is an anti-termination factor that is needed for the transcription of the delayed early genes . </Li> <Li> Delayed early genes: These include the replication genes O and P and also Q, which encodes the anti-terminator responsible for transcription of all the late genes . </Li> <Li> Late genes: </Li> </Ol> <Li> Immediate early genes: These genes are expressed from promoters recognized by the host RNA polymerase, and include Cro, cII, and N.
