The phage latches on to the new cell and to infect it.

This type of bacteriophage does not kill the host cell right away, rather the phage genome integrates into the bacterial chromosome and becomes apart of the host. Then, as the host divides into daughter cells the phage genome is also replicated. Eventually, the host cell becomes stressed, the phage genome exits the host, makes more phage particles, and then the virus exits the host DNA resulting from lysis.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

The host (bacterial cell) divides into 2 daughter cells and each of them has the prophage DNA this continues until the cells get stressed out until the viral DNA exits the host DNA.

The advantage of the Lysogenic Cycle

The steps for both the Lytic and Lysogenic cycle of replication include:
- Attachment
- Penetration
- Integration and host cell division (unique to the lysogenic cycle)
- Biosynthesis
- Maturation
- Lysis

Steps of Bacteriaphage Replication

The phage DNA is incorporated into the host genome.

Integration of Bacteriophage

The production of of new viral components from phage DNA replication. 

Biosynthesis of Bacteriophage

Penetration of Bacteriophage

Mature viruses burst out of the host cell and into the environment to infect new cells.

Lysis of Bacteriophage

When the cell is under stressful conditions the prophage DNA is excised from the bacterial chromosome so that it can enter into the lytic cycle where the cell is destroyed.
