5.7B **Biology Only** - Lifecycle of a Virus Flashcards
What do viruses require to reproduce?
Viruses require host cells to reproduce.
What is the first step in the lytic pathway?
Using host cell machinery, the virus replicates its DNA.
What happens after the virus DNA is replicated in the lytic pathway?
The DNA is assembled to form new virus particles.
What occurs when the host cell is full of virus particles in the lytic pathway?
The host cell bursts in a process called lysis.
What happens after lysis in the lytic pathway?
The process is then repeated with nearby cells.
What is the first step in the lysogenic pathway?
The virus uses restriction enzymes to insert its DNA into the host cell DNA or plasmids into the host cell cytoplasm.
What happens when the host cell replicates in the lysogenic pathway?
The viral DNA is also copied in this process.
What begins after the host cell replicates in the lysogenic pathway?
The lytic cycle begins, starting with the assembly of new viral particles.
