Learn about Viruses – The most “living fault” entities on Earth

In the days when epidemics were raging, we all tended to be more interested in pathogens, namely bacteria and viruses. Bacteria and protozoa in general are familiar to us in high school, but the virus is not mentioned much. So hopefully the following article will help you understand a little more about these “living bug” entities.

Viruses are one of the most diverse biological entities in nature. However, up to now, although there are still millions of different types of virus, we have only recorded 5000 types. One of the biggest difficulties in studying viruses is that they are so small and most viruses cannot be seen with an optical microscope.

Virus is extremely simple structure, including 2 to 3 main parts as follows:

    The genetic material is made up of DNA or RNA, which are long molecules carrying genetic information. A protein crust – called the capsid – is responsible for protecting the genome; and in some cases a section (3). An outer layer made of lipids that envelop the protein shell when the virus is outside the cell.

There has been much debate among scientists about whether the virus can be considered a living form. It has no cellular structure (the most basic unit of life) but has the ability to genetically, reproduce and evolve according to natural selection processes. It has some basic characteristics of life but is not complete. So they are considered “creatures on the margins of life”. Basically they are not really alive, they are just an entity that exists with life.

As mentioned above, viruses are very diverse, they have many different shapes and sizes, from spiral, spherical, 20-sided block or more complex shapes. However, the mode of operation is the same. Because viruses are not fully living organisms, they cannot metabolize themselves to grow or divide. Instead, they will use the host cell’s metabolism and metabolism to make multiple copies of themselves, assemble themselves and continue to disperse. Viruses do not move by themselves to actively attack host cells, but they spread themselves in the environment, waiting until they meet the appropriate host to attach to.

Because of its simplicity, the virus works very well. They multiply a lot, many mutations lead to evolution and rapid adaptation to new conditions. That’s what makes the virus so dangerous. Basically, we “live” in a very “buggy” way. They do not actually live but parasitize on living cells and then take advantage of that cell to multiply and continue to parasite more cells. The virus’s parasite, self-replication and spread often kills host cells, lethal to unicellular and pathogenic organisms, and depletes the vitality of multicellular organisms.

Each type of virus will have a specific host amplitude, which means that each type of virus will only be able to parasite on a certain host or group of hosts. For example, smallpox virus can only be harmful to humans, while rabies virus has a wider host range, can parasitize in many different mammals. The HIV virus is focused on targeting important cells in the human immune system.

On the other hand, even though viruses have a very faulty way of “living” to harm an organism, they also play an important role in the evolutionary history of life. They serve as a horizontal means of transporting genes, enabling organisms to share genes directly to each other, contributing to biodiversity and promoting evolution.

In short, although viruses are harmful to almost every living thing on earth, they have made important contributions to the history of life. Without them, the world we still know would be very different. Even though they’re not good, they are still useful in certain ways.
