Question
Chapter 26, Problem 7A
Summary Introduction
Introduction: Any groups of viruses that infect and replicate within the bacteria is referred to as a bacteriophage. They inject their own genetic material into the bacterial cells and use the biological machinery of the bacteria for their reproduction.
