Answer:
Bacteriophages have a lytic or lysogenic cycle.
Explanation:
The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion.
Opsonization.
Explanation:
- Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.
Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.
Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.
