Bacteriophage λ, after infecting a cell, can integrateinto the chromosome of the cell if the repressor protein, cI, binds to and shuts down phage transcriptionimmediately. (A strain containing a bacteriophageDNA integrated into the chromosome is called a lysogen.) The alternative fate is the production of manymore viruses and lysis of the cell. In a mating, a donor strain that is a lysogen was crossed with a lysogenic recipient cell, and no phages were produced.However, when the lysogen donor strain transferredits DNA to a nonlysogenic recipient cell, the recipientcell burst, releasing a new generation of phages. a. Why did the mating with a nonlysogenic recipientresult in phage growth and release, but the infectionof a lysogenic recipient did not?
Bacteriophage lambda is integrated in DNA of a host cell, which is exposed to UV light in a body of water in the environment. Describe the sequence of events that occurs in its life cycle.

Let’s suppose a drug inhibits the function of the N protein. Would such a drug favor the lysogenic cycle, favor the lytic cycle, or prevent both cycles from occurring?
Understanding the life cycle of Plasmodium is important and we know that it is spread via mosquitos.
