Viruses are not cells, but tiny particles containing some nucleic acids (DNA or RNA) and a capsid (a protein coat) Viruses cannot live or reproduce on their own; therefore they are not considered a living organism Because of this Viruses are hard to classify Viruses force the infected host to replicate its DNA and then takes over the cell



EXAMPLE 1 EXAMPLE 2 EXAMPLE 3 EXAMPLE 4



Questions for Monday's Lecture - Virus Parts, Types, and Examples  1. What is a nucleic acid? and Describe its location on a virus. 2. What a capsid? and Describe its location on a virus. 3. Name and describe four shapes viruses might have; and give an virus example for each shape.  4. Explain why Viruses are not considered living. (Give 2 explanations from the notes)  5. Give another name for the flu (influenza).  6. Give two examples (names) of the common cold.  7. Which kingdom would the common cold attack? <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%; text-align: center;"> (Remember the 5 kingdoms? -Monera, Protista, Fungi, Plantae, Animalia) <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%; text-align: center;"> 8.

Remember - Be Creative (be funny and original but use actual info and explain things)!

**// 1. how viruses go through the process of either the lytic and lysogenic cycles and what the function/structure of viruses are for in that process (capsid, DNA or RNA, attachment fibers, ect...) //** **// 2. types of viruses, their attributes, their symptoms, and prevention (research symptoms to be sure) (plant viruses-tobacco mosaic virus or tomato mosaic virus; Bacteria viruses-T4 Bacteriophage; animal viruses- Rinovirus, Adenovirus, Orthomyxovirus, HIV, Rabies, Smallpox, Chickenpox, Cowpox, Rubella, H1N1, or SARS -Coronavirus) //** in the comic strip.
