Final answer:
Viruses that infect bacteria are called bacteriophages.
Step-by-step explanation:
Bacteriophages, often referred to as phages, are viruses that infect and replicate within bacteria. They are the most abundant biological entities on Earth and play a crucial role in the regulation of bacterial populations in various environments. Bacteriophages have been extensively studied for their potential applications in medicine, biotechnology, and environmental science.
The viruses that infect bacteria, such as in Hershey and Chase's experiment, are called bacteriophages. Bacteriophages are a type of virus that specifically infects bacteria. They have a protein coat and a nucleic acid core, which contains the genetic material.
