During the lysogenic cycle of lambda (A) phage the phage genome is integrated in the host chromosome where it is passed on to daughter cells through binary fission. the phage DNA is copied and accumulates in the cytoplasm. Then a trigger causes capsid proteins to be made and phages are assembled. the product of one prophage gene is made and it activates most of the other prophage genes. the viral genes immediately turn the host cell into a lambda-producing factory. Then the host lyses.

What type of infection is caused by a temperate phage?

Consider a hypothetical phage whose DNA replicates exclusively by rolling circle replication. A phage with radioactive DNA in both strands infects a bacterium and is allowed to replicate in a nonradioactive medium. Assume that only daughter DNA from the elongated branch ever gets packaged into progeny particles.    What fraction of the parental radioactivity will appear in the progeny phage? How many progeny phage will contain radioactive DNA? What is the fundamental difference between the initiation of θ replication and that of the rolling circle?
