Certain environmental conditions such as UV light are known to activate lysogenic λ prophages and cause them to progress into the lytic cycle. UV light initially causes the repressor protein to be proteolytically degraded. Make a flow diagram that describes the subsequent events that would lead to the lytic cycle. The xis gene codes for an enzyme that is necessary to excise the λ prophage from the E. coli chromosome. The integrase enzyme is also necessary to excise the λ prophage.
