Intro to Viruses

Pathogens

Pathogens cause disease. Examples of pathogens include:

- Bacteria (salmonella, pneumonia)

- Fungi (althlete's foot, ringworm)

- Viruses (cold, flu, Covid)

Recall The Cell Theory

All organisms are made of cells,
Cells are the basic structures of living things,
All cells come from pre-existing cells.

Viruses are not cells

Viruses are not truly living because they are not cells. They do have some things in common with organisms, such as containing genetic material. A virus's genetic material can be either DNA or RNA.
