Viruses VS Cells
By: Amanda Nguyen
Viruses
HIV
Weakens a person’s immune system by destroying important cells that fight disease and infection
Influenza
Infects your respiratory system - your nose, throat and lungs
Bacteriophage
a group of viruses that infect bacteria
Animal Cell
Plant Cell
Lytic & Lysogenic Cycle
Lytic Cycle
- Attachment - The virus enters the human body and starts looking for a host cell. Once one is found, the uncurable disease attachs to the cell.
- Entry - The virus injects the RNA into the host cell for it to be mutated.
- Mutation - The RNA and the host's DNA bind together into a new strand of DNA.
- Assembly -
- Release - FInally, the replicated virus is placed into the blood stream. Then, the process repeats upon it self until the host in dead.
Examples: Influenza & Pink Eye
Lysogenic Cycle
- Mutation - The same as the Lystic System, the RNA and DNA fuse together into a new strand.
- Prophage - The cell undergoes the division process. This step is similar to the Metaphase and Anaphase in mitosis.
- Replication - The new DNA strand is copied and undergoes the finally step.
- Cell Division - The cell will separate, creating a replica of the original.
Examples: Ebola & HIV
Characteristics of Life
- Reproduction
- Metabolism
- Homeostasis
- Compose of One or More Cells
- Responds To Their Enviroment
- Pass Off Traits To the Next Generation
- Uses Some Form of Energy
Viruses are uncurable diseases that rely on cells for reproduction. Why? Viruses can't reproduce themselves because they do not have the required organelles in order to perform the lytic cycle. The same applies to homeostasis; Viruses don't have a cellular structure to maintain heat. Since viruses rely on cells and they're smaller then them, they are not compose of cells. They can however respond to their enviroment since they are able to enter the cell membrane and reproduce. When the virus goes through the lytic cycle; it passes off it's traits to it's offspring.
Questions
- The typical virus are compose of three main things; the capsid, the envelope, and the matrix.
- Every virus have some way of entering your system; some are complex and some are simple. Ebola can enter your body if you intake any of the patient's fluids. This virus can be intake through a cut, when you swallow it, or when you smell it.
- First, is Ebola; this virus targets animal cells.
- A doctor won't prescribe antibotics to you because they are meant for treating bacteria. You would need a vaccine to treat it since the Flu is actually considered a virus. Since the Flu is a virus, antibotics will not cause any affects to your body.
- They can't experience syptoms since the DNA replication process takes long amount of time. This makes it hard to detect the virus in the earleiest stages.
