参考答案:
Similarities In both cycles:
There is injection of genetic material/entry of genetic material into a host cell.
Infection of a host cell occurs in both cycles.
Replication of viral genetic material by the host cell
Proliferation/increase of the viral population occurs in both.
The differences are:
The lysogenic cycle involves incorporation of viral DNA into the host cell DNA (lytic cycle
does not).
Prophage (viral DNA) in the lysogenic cycle is replicated with host DNA/passed on to
daughter cells with host DNA and in the lytic cycle, the viral DNA is replicated independently
of host DNA.
Lytic cycle is generally has a shorter infection phase/the lysogenic cycle (usually) has a longer
infection phase.
In the lysogenic phase of infection, the host cell is not lysed (in the initial stage of
infection)/in the lytic phase the host cell is lysed.
