How big are viruses?
much smaller than the smallest bacterias (cells).
Virus
A tiny nonliving particle that enters and repredouces in a cell.
Infectious Disease
Illnes caused by pathogenic microorganisms
Virus that affect animals

Examples of shapes and viruses
S = Tube

Lysogenic- When viruses dont immideatly affect you because the cell is making copies of itself w/the virus in it.
Pathogen
A bacterium or microorganism that can cause disease
Contagous
Can be spread to others
Gene Therapy and Viruses
Attach genetic material onto viruses
Virus is messenger and delivers genetic material to cell
Type of Vaccine: Inactive
A pathogen has to be killed and they are very hard to make
Why are surface protiens of a virus inportant?
Allow the virus to invade the cell, only works for certain type of cells
