Definitions:

Prophage DNA

The DNA of a temperate bacteriophage that is integrated into the bacterial host's genome and replicates along with it without causing lysis.

Botulism Disease

A potentially fatal illness caused by botulinum toxin, produced by the bacterium Clostridium botulinum, affecting the nervous system.

Lytic Bacteria

Lytic bacteria are those that enter a host cell, reproduce by utilizing the cell's resources, and eventually cause the host cell to burst (lyse), releasing new bacterial cells.

Viral Lytic Cycle

The process by which a virus reproduces itself inside a host cell, ultimately causing the cell to burst and release new virus particles.
