Why Are Viruses Bad

A virus is a very small and tiny non-cellular organism that can reproduce only by infecting a host cell. They are basically made up of genetic material and protein. This microorganism belongs to the family of viridae and genus of Virus. The term virus comes from the Latin word “virus” which means “poison”. In 1945, a scientist named Wendell Stanley discovered that viruses are made up of nucleic acids, protein and lips. Starting from that time, the study of virus became "Virology." These viruses are so tiny that it is measured in nanometer and they can only be seen in an electron microscope. Viruses are composed of a core of DNA or RNA surrounded by a protein coat. They can only reproduce by infecting living cells. The virus particles are 100

Viruses do not have the characteristics of a living thing. They have no energy metabolism and they do not reproduce independently. As a result, scientists considered viruses as a non-living thing. Viruses are not living things and they can’t to anything. On the other hand, after they enter a living cell, everything changes and they become living things. The viruses started to multiply or replicate themselves and spread bigger and bigger. There are two ways that virus replicate or multiply themselves. The first way is the Lytic cycle in which the virus attaches to a host cell and infuses the cell with its nucleic acid. The acid takes the host cell hostage. Then, the virus started to multiply with the nucleic acid and protein coat, producing a new virus. These new viruses continued the lytic cycle. Another cycle is called the Lysogenic cycle. The viruses entered the host cell, but they are slow in multiplying and it includes the HIV virus and herpes. While the viruses’ nucleic acid is present in the chromosome, it is not active so it doesn’t immediately affect the cell’s function. But then, it separates from the genetic material of the host cell and take over to multiply. The release of new viruses kills the host cell giving rise to the Lysogenic
