4. VIRUS - Definition
A Virus is an ultramicroscopic particle (from nm in diameter) metabolically inert, that is an infectious agent that replicates only within the cell of a living host, composed of an RNA or DNA core, a protein coat (capsid) and sometimes a surrounding envelope.

5. Characteristics of Viruses V.S. Characteristics of Living Things
They Grow
They Reproduce
They are made up of Cells
They Need and Use Energy
They Develop
They are Organized
They have a Life Span
They Adapt
They don’t grow
They don’t reproduce
They aren’t made up of cells
They don’t need or use energy
They don’t develop
They aren’t organized
They don’t have a life span
They Adapt

7. Types of Viruses Viruses with RNA (single or double stranded)
Viruses of protein + genetic material
Viruses with DNA (single or double stranded)
Viruses with a surrounding envelope + protein + genetic material

8. Icosahedron viruses
Enveloped viruses
Helical viruses
Complex viruses

9. Infectious Agents Viroids Prions
Are made only of Protein (they are neurotransmitters that were folded in a wrong way)
Only attacks Animals’ nervous system
Are made only of Genetic Material (DNA or RNA, Single or Double Stranded)
Only attacks Plants

10. Vaccines
Vaccines are viruses that are modified viruses that affect other viruses. They are only made of the protein coat (capsid) of the virus. It “tells” the genetic sequence of the virus, to the cells of the organism that is infected.
Antibiotics cannot destroy viruses, because viruses are metabolically inert, they aren’t alive.
They were discovered by Edward Jenner in order to fight against smallpox.

13. Characteristics Metabolically inert
Only replicates within the cell of a living host
Composed of a RNA or DNA, single or double stranded, and a protein coat named capsid
It only fulfills one characteristic of living things, and that is that they adapt
It varies from size nm
