temperate phage infections: LAMBDA
immunity to superinfection
Lysogen can't be infected by another related phage
extrusion
phage particles are assembled as the exit the cell
lysogenic infection
process by which a virus embeds its DNA into the DNA of the host cell and is replicated along with the host cell's DNA
consquences to lysogeny include
immunity to superinfection lysogenic conversion
Through the process of phage ______________ , a prophage is excised and enters the lytic cycle
induction
In the replication of temperate phages, the excision of the prophage leads to the transition from a lytic to a lysogenic infection the transition from a lysogenic to a lytic infection the inactivation of the virus and initiation of the lysogenic cycle the inactivation of the virus and cessation of the lytic cycle
the transition from a lysogenic to a lytic infection
lysogentic conversion
a change in the phenotype of a lysogen as a consequence of the specific prophage it carries
repressor protein
a regulatory protein that binds to an operator and blocks transcription of the genes, essential for maintenance of the lysogenic state
True or false: Lysogens are more susceptible to reinfection by the same type of phage.
false
True or false: When a bacterial culture is infected with a temperate phage, all particles of the phage will lysogenize their host.
false
Temperate phages are more likely to enter the lysogenic cycle when bacterial cells are ______.
growing slowly
Lysogeny is best described as
integration of the viral genome into the host chromosome
induction
the process of a prophage being excised and entering the lytic cycle
Replication of temperate phages and lytic phages have which steps in common? Multiple select question. Integration of the viral genome into the host genome Biosynthesis of viral components Release Assembly Attachment Genome entry

During the process that leads to a lysogenic infection, what inserts the phage DNA into a bacterial chromosome?
integrase
During the process that leads to a lysogenic infection, which of the following inserts the phage DNA into a bacterial chromosome?
integrase
Fill in the blank question. Lysogens are protected against infection by the same phage because the phage-encoded repressor protein binds to the ________________ on the incoming phage, preventing expression of the phage genes.
operatorf
In a lysogenic infection, the phage DNA that is incorporated into the bacterial host genome is called a ______.
prophage
