How virus infect the host? This is one of the question that people want to know. This question could answered by a virus named bacteriaphage. Bacteriaphage is the virus which is not infect human, animal or plant cell. This virus found by two scientist, Frederick W Twort and Felix d'Herelle. Because of their invented people more understand about virus and how its infect the cell. bacteriaphage has a simple structure and its host bacteria , for example Eschereria coli also has a simple structure if we compare to the animal or plant cells.
how bacteriaphage infect bacteria cell? There is three phase for this virus to infect the bacteria cell. The first phase is absorbtion and penetration phase. In this phase, virus's terminal tail attach / absorb to bacteria's cell wall and then virus release some enzyme which penetrate bacteria cell wall. Then, virus release its genomic information called DNA / RNA into bacteria cell.
Second phase is called replication and assambling phase. This phase is marked by new virus synthesize, its happen when virus gene information was controlled bacteria metabolic process to produce virus nucleic acid.
The last phase is called lisis phase. This phase is marked by the exploded of bacteria's cell, it happen when virus produce more new virus then it makes bacteria cell explode and release new viruses. When new viruses release to environment, it will infect other cell bacteria and start the phase over again.
