Why Are Viruses Alive
Are viruses alive? With new evidence surfacing every day, this is the question that many scientists ask. Based on the article and the video, viruses may actually be alive. Viruses can only replicate inside the living cells of other organisms. Therefore, it would seem that a virus is just dead matter. But, because a virus adapts, multiplies, and thrives, it is no doubt a living agent. Viruses also reproduce. They may need the cell of the organism to do so, but that doesn’t mean they aren’t still multiplying and reproducing just like living cells. Furthermore, viruses grow and change, or rather evolve. “Influenza viruses can evolve in a gradual way through mutations in the genes that relate to the viral surface proteins hemagglutinin and neuraminidase.”

    Viruses – A viruses is a small capsule that holds DNA or RNA, viruses, unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce, for example: ‘Human Body’. When a virus enters the body, it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure.…

    A virus is a small infectious agent that replicates only inside the living cells of other organisms. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell to produce many more viruses. Viruses can infect all types of life forms, such as animals and plants to microorganisms, including bacteria and archaea.…

    Flu Virus Change

    • 578 Words
    • 3 Pages

    Influenza viruses are constantly changing. This is why they emphasize getting your yearly flu shot. An interesting feature of the influenza virion is its tendency to “drift and shift” ("How the Flu Virus Can Change: “Drift” and “Shift”." Centers for Disease Control and Prevention.). Pathologists coined this phrase when they discovered an antigenic drift in the DNA of an influenza strain. These changes are usually not big enough to affect our immune system’s ability to identify a certain strain. Over time however, these genetic drifts can accumulate and create enough of a difference in the genetic makeup to allow the virion to infiltrate the human body without being recognized. Shifting is the less common of the two, but is more aggressive. It occurs when new Hemagglutinin and Neuraminidase proteins emerge, completely changing the subtype of the virus. The change happens so quickly that…
