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

  1. Excision requires two host proteins and two virally-encoded proteins.

  2. Integration requires a viral-specific protein, called integrase.

  3. RecA protein is required to catalyze the insertional recombination event.

  4. The excision event relies on different sequences than the integration event.
