Premises
Virulent phage
Responses
Enzyme that can make DNA from RNA.
E. coli phage.
During this process, DNA is transferred from one cell to another through a cytoplasmic bridge.
When an animal virus remains in the cell in an inactive form.
The cycle in which a virulent phage kills the bacterial cell by lysis as the phage is released.
This cycle begins when the lambda phage chromosome integrates into the host cell's DNA by crossing over. Once integrated, the lambda genes are mostly inactive.
Integrated viral DNA.
Includes phages such as T2 and T4.
Layer of protein surrounding the viral nucleic acid.
Transferring DNA using a virus.
Virus with an RNA genome that is copied into DNA.
Type of virus that does not kill a host cell in every replication cycle
Type of virus that kills a host cell in every replication cycle
