To see the virus-cell,s that they are connected to the human body. They have a special receptor to connected the virus to a human. When they are connected to the human cell have also the special receptor. If we see the cell of the virus they have a special type of long rod-like shape structure. That is used by the cell and connect to the other cell or human. For us, we have known that it injects the RNA of the virus into the human cell and replicated inside the cell. And after the along time or replication, it takes out of the cell and different its shape, which is very hard to detect and killed it. Because it won't have the proper shape. coronavirus fact: In the case of coronavirus, it is specially designed as it is propagated from one place to another place. The genetic changes from those cells or virus which effectively the animal and know it affects human beings. If that technology is to stand in the world it is very dangerous for the life of
History: The first time this virus is discovered in China(city Bohan).The prevention or precautions are if you follow you will be safe from this disease. Actually, this is not the disease this is a genetically modified virus. It first time this disease is found in animals and then converted into a human. Types: There are two types of viruses. 1)DNA virus. 2)RNA virus. 1)DNA virus: Mean: Those viruses which are propagating due to DNA. Explanation: Ase we can know that DNA is the property of polymerase(enzymes). Which is the ability to repair the DNA sequence, as it is made the first stand and then come at the second time correct the sequence of the DNA. due o this property te DNA viruses change are not propagate that much, and it is finished after some time or it is converted to a genetic disorder. 2)RNA virus: Mean: Those viruses which are propagating through RNA.

Definition: "The internalization within the cell". Diagram: The internalization of the cell occurs in so many steps,s. Which are given below: 1- Bending of the cell membrane. 2-Movement of the cell. 3-Enclosing of the cell. 4-Secreting enzymes. Let's discuss one by one 1-Bending of the cell membrane: The bending of the cell membrane occurs due to some receiver on the cell membrane.when some outside cell,s come to the body some cells,s are et them with the process of self-eating. The cell membrane bends and tries to offer the cell to come in. 2-Movement of the cell: When the cell moves from the outside to inside. It is moving into the cell. 3-Enclosing of the cell : After the moving moment of the cell from outside to insid
