The lysogenic virus then became the information storage center for the cell, while the cell retained its capacities for gene translation and general function despite the viral genome s entry.

Bacteriophage lambda encodes two repressors : the Cro repressor that acts to turn off early gene transcription during the lytic cycle, and the lambda or cI repressor that is required to maintain lysogenic growth.
33.
A process known as lysogenic or phage conversion changes the properties of the bacteria cell; this is possible because the prophage itself contains genes that can present new properties into the bacteria cell or host cell.
34.
All of the known temperate phages employ one of only three different systems for their lysogenic cycle : lambda-like integration / excision, Mu-like transposition or the plasmid-like partitioning of phage N15.

We plan to talk about the lysogenic phase of this temperate bacteriophage which is maintained by a repressor which represses all other genes except the speA gene which results in continuous production of the toxin during the lysogenic phase.

The genome is especially rich in Chi sequences recognized by the bacterial recombinase RecBCD . The genome contains two origins of replication : oriR which replicates it during the lysogenic cycle and oriL which replicates it during the lytic stage.

However, when the Hfr parent was lysogenic, lysogeny ( i . e ., the prophage ) was not inherited by any of recombinants, which were recovered by growing them as colonies on the appropriate agar medium.
39.
The distinction between lysogenic and lytic cycles is that the spread of the viral DNA occurs through the usual prokaryotic reproduction, while the lytic phage is spread through the production of thousands of individual phages capable of surviving and infecting other cells.

Much of his early research with the university was in biochemistry and virology, and during the 1950s, 1960s, and 1970s, he contributed to the university's influential " virus project ", studying bacteriophages and the lysogenic cycle.
