Question
Chapter 16, Problem 4WIO
Summary Introduction
To explain:
The reason for lytic viruses being better suited as agents of “phage therapy” than the lysogenic viruses and how would an individual tests whether such a treatment would be effective and would an individual be willing to take a “viral antibiotic”.
Concept introduction:
Bacteriophage is a virus that infects the bacterial cell. The structure of bacteriophage is very much similar to the structure of the viruses. There are two types of viral replication strategies present in the bacteriophage named as lysogenic infection and the lytic infections.
