Louis Pasteur is best known for developing the process of pasteurization. Pasteurization involves the heating of a liquid to a specific heat for a certain length of time then immediately cooling it.

A phage that can enter into lysogeny with its host. A phage that can become a prophage.
The bacteriophage blinds to the bacterium.The phage DNA enters the host cell.The host DNA is digested, new phage DNA forms, using nucleoleotides from former host DNA.The host cell transcribes and translates the phage DNA, producing phage proteins.Assembly of new is complete. A phage-encoded enzyme causes the cell to lyse.New phage are released to start the cycle again.
Phage DNA that is integrated into a host's cell chromosome is a bacteriophage. They behave as lytic or lysogenic. Lytic breaks open the host after replication, , lysogenic does not destroy the host.
Once inside the host cell, phage DNA utilizes the host cell's machinery to replicate itself. It takes over the cellular processes and redirects them towards the production of new phages. The phage DNA is transcribed and translated to synthesize the necessary components for phage assembly, ultimately resulting in the formation of progeny phages inside the host cell.
temperate refers to the life cycle some phages are able to perform. A temperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium.The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).So they are both the same in that they both require a host cell to reproduce. They both can have lytic lifecycles but only the temperate phage can "hitch a ride" in the host cell by integrating into the genome.

c. Repression of the phage genome - A phage coded protein, called a repressor, is made which binds to a particular site on the phage DNA, called the operator, and shuts off transcription of most phage genes EXCEPT the repressor gene. The result is a stable repressed phage genome which is integrated into the host chromosome. Each temperate phage will only repress its own DNA and not that from other phage, so that repression is very specific (immunity to superinfection with the same phage).Reference: http://pathmicro.med.sc.edu/mayer/phage.htm
