Is a virus alive?
What are the structures of viruses? How does a virus “adapt”?
Looking at my virus top ten notes, notice five ways to debate that a virus may or may not be alive.
While it does show some similar activities of life, a virus is not a cellular and self maintained structure.
The riddle is..how did a virus gain DNA or RNA. In fact, it is truly the first “chicken verses egg” story.

Answer Questions |
| Topic
Number Two |
How do we classify a “non living thing” and what are some myths about viruses?
The old system say that viruses can be classified by the host that they infect ..
The new system is more complex! http://www.nlv.ch/Virologytutorials/Classification.htm
http://www.news-medical.net/health/Virus-Classification.aspx
http://www.slideshare.net/AliaNajiha1/chapter-2-classification-of-virus
From these links, 1. How has the classification of viruses changed with the increased information on viruses? 2. Can viruses evolve? 3. Why do standard methods of taxonomy not work for virus? 4. What evidence for viruses being alive are being used related to their classification?
Looking up myths about viruses and the first thing you find is computer viruses! Which came first the actual biological virus or computer viruses is quite obvious.

Critical thinking challenge 1. Is the zombie virus a real threat? 2. Can you get a virus by being in a room that an infected person has been in? 3. Is Ebola the worst virus that has evolved on earth? 4. Are all viruses fatal? 5. Can getting sick with a virus actually help you? 6. Why have myth about viruses more common now than in the past?

What is an “infection” and virus infective cycles
With all online evidence..make sure to check your source

Virus cycles http://www.jblearning.com/samples/0763729329/29329_CH03_046_069.pdf
Lytic https://en.wikipedia.org/wiki/Lytic_cycle
Latent https://en.wikipedia.org/wiki/Virus_latency
Mutagenic https://en.wikipedia.org/wiki/Mutagen
Questions 1. Can you explain why some infective viruses are not fatal? 2. Can you describe an example of an example of latent cycle? 3. Can you draw a lytic cycle? 4. Why do all “life cycles” of virus include a bacteriophage? 5. What is a bacteriophage and how is it structure linked to how and who it infects? 6. What is an example of a mutagenic cycle? 7. How is a mutagen similar or different than a flu virus? 8. What is an example of a retrovirus and why is it unique?

| Take Home Message | A virus is a biological paradox!
· It is both alive and not alive. · It is both lethal and yet can be linked to evolution. You take antibiotics for bacteria yet they are of no use for viruses. Truth is stranger than fiction.
