What is coronavirus ??
Now Corona is hanging in the mouth of every person in the world. So that what is Corona?
Does anyone think that such a question can be questioned? So the point here is not to ask if anyone has heard of Corona. As everyone now knows, the corona is a very bad, nasty and killing bacteria of thousands of people - just like the bacteria, amoeba and other bacteria that bring us disease. That is, it is also a micro-organism. But, that's only half right, not 100 percent. Why?
Because corona is a type of virus. We think of viruses as organisms. However, it shows the organism's appearance and behavior only when it enters the cell of an organism. Otherwise, it does not look like an organism, nor does it show the behavior of an organism. According to what we understand so far, organisms generally have to have at least breathing (taking oxygen and carving dioxide out of the body), eating, eating, fertilizing, and producing offspring. But they do not perform any action until the virus enters the cell of an organism. Even after entering the cell, it does not perform any of the above-mentioned activities other than multiplying it, such as photocopying itself. And how do you call it living? But, because it grows inside the cell, it does not get any. If inanimate, the numbers would not increase. Because of these things, it would be advisable to treat the virus as an inanimate and inanimate object.
To understand the coronavirus, it is appropriate to first mention some of the facts that science has discovered about the virus.
Scientists have proven the fact that the origin of life on Earth billions of years ago, when it was evolutionary, was initially composed of amino acids, then nucleic acids and then protein compounds. All of these processes took place when the atoms of the elements in the earth's atmosphere were composed of molecules of different compounds, and even the various compounds were chemically combined to form new terrestrial objects. Nucleic acid had such a quality that it could make another copy of its own kind. Later, the nucleic acid molecules bind to the chains and form large molecules such as RNA and DNA. The same RNA and DNA molecules became the basis for life. Because they started to make another copy item similar to their own. But, that was not life. Life only developed later.
As the Earth's atmosphere changed, cells became RNAs and DNA cells. In the cell, the RNA and DNA chains were protected within the nucleus. Such an organism evolved as a single cell organism, similar to the bacteria present. Scientists have discovered the fact that the same bacterium has evolved from the early single-celled organisms to the simple multicellular organisms and subsequently to the later evolution of complex multicellular organisms.
At 29, the great scientist Charles Darwin said that organisms are constantly changing and that changes are made by simple and micro-organisms, from the natural systems that are adapted to the environment and environment, to the offspring that transcends ancestry. His idea was called evolutionary, and it is on this basis that the idea of evolution of complex and larger types of organisms from simple organisms to the idea of scientific evolution is now accepted by all. Continuing subtle changes in such organisms is the reason for the sudden change in the genetic structure, namely mutation, said Hugo de Frieze, another scientist in the Netherlands (19-21). His theory is called the mutation theory.
Mutations in the early stages of life on Earth opened the way for the virus to evolve to real life. In fact, the virus, which is the only form of RNA or DNA that precedes the formation of cells for life, is the virus. This is the reality of the virus. The virus still contains organs containing RNA or DNA and other protein molecules. The virus, therefore, is the micro-object between life and the lifeless particulars of life on earth. As soon as this material enters a cell, copies of it begin to form, as they contain RNA or DNA chains. These chains are molecules made up of molecules with the same genetic ability to reproduce.
Coronavirus is also one of those viruses. The outer covering of the virus consists of thorn-like organs. They are called spikes. These spikes are crown-shaped. So the virus was named Corona by the name of the Crown. The coronavirus first appeared in Guangdong Province, China, in November. It is not yet clear from which animal the virus, which is said to have evolved in the animal body and transmitted to humans, has yet to be identified. However, many believe that it has evolved into the skin and transmitted to humans through some other animal. The virus was transmitted to humans on days 1 and 2. Since the virus has a serious impact on the human respiratory system, the disease is known as SARS (Severe Acute Respiratory Syndrome). And, the virus is called the SARS coronavirus, or SARS-CoV. SARS-Cove killed 3,000 people from 3 nations, including mainland China, Hong Kong, Vietnam, Taiwan, Taiwan, Thailand, Singapore, Canada, etc. (See: http://who.int/)
Another coronavirus similar to SARS-Cove appeared in Saudi Arabia in the West Asian country in the 5th. West Asia is called the Europeans Middle East. So the virus was named Middle East Respiratory Syndrome (MERS-CoV).
Mercer-Cove infected 3,949 people from six nations of the world, including Algeria, Austria, Bahrain, China, Egypt, France, Germany, Greece, Iran, Italy, the United States, and 1 percent of the infected lives (3). http://who.int)
According to scientists and doctors, now the first new coronavirus, the novel coronavirus, developed in China, with a mutation. Being a new coronavirus, it was initially called the Noble Coronavirus. Noble means were new. It was later renamed COVID-19 due to its appearance in 1929. Of (Co) means corona, vi means viral, and D means Disease. It was recently renamed 'SARS Cove-1' by the World Health Organization (WHO). It was named as the second generation of the new virus to cause SARS disease, which appeared in the 5th.
How does the new virus develop?
The principles of mutation and natural selection have been discussed above. Scientists say that when genetic differences in organisms occur, natural selection begins. Genetic variation means genetic variation in a portion of a population. Genetic differences come from the two main sources of viruses: 1. Recombination, and 3. Random mutation.
१. Recombination:
Hereditary substances are DNA or RNA. In recombination, the same genetic material is exchanged. It is important to remember that the genetic material or genus determines the quality of the virus. As stated above, when a virus enters an organism, it begins to function according to its own quality, which we call infection. According to scientists, when two different viruses infect the same cell, there is a possibility of recombination. Two different viruses circulating within the same cell will go into the host cell. In such a combination, different DNA fragments of DNA or RNA can be joined to one another. This leads to the creation of new DNA or RNA beads. A new type of DNA or RNA is a gene that carries a new quality. Thus the process of becoming a new genus is restructuring. The new genetic structure creates new viruses with new properties. Such new viruses produce many replicating viruses using biological substances inside the cell, and these new viruses come out by stimulating or destroying the organism. Such new viruses are called reassortant viruses.
According to scientists, flu viruses are the masters of the virus. That is, they are skilled in the reproductive process. They consist of eight RNA fragments carrying one or a few bacterial particles. When two different influenza viruses reach the same cell, some new viruses are formed within the cell. RNA fractions have already been synthesized in new viruses created. For example, if human influenza virus and bird influenza virus become infected together with the pigs 'cells, then the RNAs of those two viruses in the pigs' cells can be synthesized to form new viruses. And, many copies of that new virus are made up of viruses, and they break down their cells. Thus, the evolution of new viruses is usually normal in nature. Scientists say that H1N1, the swine flu virus that has been infected with H1N1, has spread in 29 years. (See: www.khanacademy.org)
२. Random mutation:
Mutations in the virus mean permanent changes in their genetic material (ie DNA or RNA). It is noteworthy that the virus is copied by the DNA or RNA contained in it. So if the DNA or RNA structure is accidentally changed during copying, then the new copy virus becomes different and all the copies it produces are different from its parent virus. These new viruses carry a new character in terms of quality and infection. Such mutations occur more rapidly in the RNA virus than in the DNA virus.
Remarkably, the sars virus is an RNA virus. Scientists say that the current Covid-29, namely, Sars Cove-1, has evolved due to mutations in the SARS virus. However, the exact mechanism by which the virus is mutated in humans has not yet been determined. All the information that has come out about this now is just a guess. Someone said that the skin was mutated to the person. Someone said that the serpent had mutated and moved on man. However, even though mutations are transmitted to humans, one thing that many have found is that the virus is transmitted from an old virus to a human in some animal body. It is certainly a deadly bacterium that originated according to the theory of mutation by scientist Hugo de Freiz and the choice of nature of scientist Charles Darwin.
