Nonliving infectious agent that can cause disease. *Not in a kingdom Virus Nonliving infectious agent that can cause disease. *Not in a kingdom

Non-Living vs. Living Properties Non- Living Properties Living Properties No Nucleus No Organelles Doesn’t Grow Doesn’t Eat No Waste Needs a Host (parasite) Replicate Genetic Information

Shapes of Viruses Phage- infect bacteria 3. Adenovirus- polyhedral 2. Helical- TMV (plants) 4. Round- Influenza

Virus Structure Genetic Material- DNA or RNA Protein Coat- Protection around genetic material Tail- attaching onto cell surfaces.

Viral Replication

Viral Diseases Vaccine- putting a weakened virus in the body so immune system can recognize and destroy it. Examples Measles Mumps HIV Chicken Pox/ Shingles Hepatitis West Nile Herpes Ebola
