| Question | Answer |
|---|---|
| VIRUS | microscopic particle that invades living cells |
| host specific | a virus can only attack certain cells |
| The Lytic Cycle | 1. the virus attaches to the host cell 2. the virus injects its dna into the host cell 3. the host cell is destroyed and the viral DNA replicates 4.new protein coats form around the viral DNA, the cell bursts open and newly made viruses are released |
| white blood cells | can surround and kill viruses |
| antibodies | if the virus is not destroyed by a white blood cell, specialized cells called the antinbodies join the fight...they work in two ways...1. destroy virus directly 2. attach and hold on to the virus until more white blood cells are made |
| Interderon | interfearing when viruses are produced |
