A
Human Chorionic Gonadotropin
2
Q
Explain lytic cycle
A
- bacteriophage interacts with bacterial surface receptors (lipopolysccharides)
- phages tail sheath contracts, injecting genetic material into cell
- virus hijacks cell to synthesize necessary components for assembly of a new virus
- the cell then lyses when it gets too full
3
Q
Explain lysogenic cycle
A
- phage genome integrates into bacterial genome and becomes part of the host.
it is called prophage

7
Q
What are the 3 physical barriers against pathogens in the human body?
A
- skin
- mucus
- cilia
8
Q
What are the chemical barriers against pathogens in the human body
A
- hydrochloric acid
- lysozyme
9
Q
What is needed to make monoclonal antibodies?
A
- mouse B-lymphocyte and myeloma are fused to form a hybridoma. this then rapidly synthesizes.
10
