The bacteriophage can lysogenize after infecting a bacterium, i.e. integrate into the host bacterial chromosome by site-specific recombination, and may reside there for many generations before an excision event regenerates the viral genome in an infective form. Which one of the following is not a component of these events?

#SCPH06 I Botany

Excision requires two host proteins and two virally-encoded proteins.
Integration requires a viral-specific protein, called integrase.
RecA protein is required to catalyze the insertional recombination event.
The excision event relies on different sequences than the integration event.
