Sir, what exactly is a virus and what is its purpose in our daily life.
Class make sure to study your virus thoroughly.
Genetic Information: The DNA/RNA of a virus. This is what is injected into the cell during the replication cycle.
A virus is a microscopic parasite which can infect living organisms and can cause disease.
There are two ways that viruses can replicate. Either through the Lytic or Lysogenic Cycle. In the Lytic Cycle the virus injects its DNA inside the cell. Then, when the DNA is injected its starts to replicated and transcribed. Once transcribed the protein is made and then the virus begins being constructed and finally, the viruses burst out of the cell wall.
Now in the Lysogenic Cycle the Virus attaches to the cell and injects its DNA as well, but the difference is that in the Lysogenic Cycle the virus stays dormant and allows the host cell to replicate more cells with the viral DNA. After a while the viral DNA will be activated causing the host cell to make way more viruses and then bursting out of the cell.
Protein Coat: Also known as a Capsid provides protection for the virus. It holds the viruses genetic material.
Viruses have three main general structures.
A way to attach to a cell: This comes in many different ways for any virus. This is the way the virus attaches to the cell itself.
A main virus that is known by many is HIV which means its perfect for an example. Human Immunodeficiency Virus or HIV attaches to the cells in your body. The virus then infects the cells and uses them as a place to multiply. In doing so, the virus destroys the ability of the infected cells to do their job in the immune system. The then loses the ability to fight many infections.
