Explore the biology of bacteriophages, their structure, life cycle, and role in science with Khan Academy's detailed educational resources.

Bacteriophages, just like other viruses, must infect a host cell in order to reproduce. The steps that make up the infection process are collectively called the lifecycle of the phage.
