Gizmos

Virus Lytic Cycle

Release a lytic virus in a group of cells and observe how cells are infected over time and eventually destroyed. Data related to the number of healthy cells, infected cells, and viruses can be recorded over time to determine the time required for the virus to mature within a cell.

- A. Lysis occurred for zero cells in the first 150 minutes and for all 100 cells in the last 150 minutes.
- B. Lysis occurred for 30 cells in the first 150 minutes and for 70 cells in the last 150 minutes.
- C. Lysis occurred for 50 cells in the first 150 minutes and for 50 cells in the last 150 minutes.
- D. Lysis occurred for 70 cells in the first 150 minutes and for 30 cells in the last 150 minutes.
