PATHOGEN |
can cause infectious disease ex. viruses, bacteria, viroids, & prions |
|
|
VIRUS |
* infect all organism * nucleic acid DNA/RNA * protein coat capsid * no nucleus, membranes |
|
|
VIROID |
* infects plants- stunts growth * no capsid * free floating,single strand RNA |
|
|
PRION |
* protein that causes other proteins to misfold * smallest of pathogens ex. Mad Cow disease |
|
|
VIRUS SHAPE |
the arrangement of the proteins in the outer coat determines the shape of the virus |
|
|
