Explanation / Answer

Answer for question number 1 : The correct option is E ( The rupture of the bacterium)

Explanation : Lytic cycle is one of the two (the other one is lysogenic cycle) cycles found in bacteriophage life cycle.

During lytic cycle, the viral infection is followed by lysis(bursting and death) of the host cells and release of new infective phages. Examples of lytic bacteriaophages are virulent phages such as T4 and other T even coliphages.
