lysogenicity, lysogeny

1. the ability to produce lysins or cause lysis.
2. the potentiality of a bacterium to produce bacteriophage.
3. the specific integration of the phage genome (prophage) into the bacterial genome in such a way that only a few, if any, phage genes are transcribed; the integrated phage DNA behaves much as any other bacterial gene, including being passed to each daughter cell following DNA replication and cell division.
