Think-Pair-Share Questions

1. Describe how a lytic bacteriophage might possibly play a role in horizontal gene transfer in bacteria.

2. As will be seen in lab, phage typing is a technique wherein unknown strains of a bacterium are identified by using known strains of bacteriophages. How can we use a bacteriophage to identify a bacterium?

3. We saw in the previous section that a single infected animal cell may produce 10,000-50,000 viruses yet an infected bacterium can only produce 50-200 bacteriophages. Explain this.
