Is Virus Alive

Is a Virus Alive? To figure out an explanation of whether a virus is alive or not, the term “alive” will have to be defined first. With the use of the universal term used by biologists (Respiration, Regulation, Reproduction, Excretion, Growth, Nutrition, Transport, Synthesis or R.R.R.E.G.N.T.S. for short). This term can be used to classify whether something is alive or not. Viruses at its core is made of 2 different parts which includes a nucleic acid and a capsid (sometimes also a lipid membrane) (Dr. Ananya Mandal, 2013). By itself, viruses are merely passive and don’t do anything. When encountering a cell it sheds its capsid coating and chemically change the cell functions to start replicating the virus (R. Vincent, 2004). This makes it

    The definition of a virus from the Oxford Dictionary is, an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host: To me that means that they are these tiny molecules that are not cells, but able to multiply, but only inside of the cells of the person the virus has gone into. Viruses are not living things. They do have many things inside them that a living thing may have like proteins, nucleic acids, carbohydrates and Lipids. the problem is that they can't function…

    In The Kill Order, Earth has been hit by sun flares, which destroy vast amounts of land and creates intense radiation. The Earth’s population is cut in half, but resources are low, and the surviving population is large. Trying to prevent the rapid depletion of resources, the Population Control Committee (PCC) propose the release a deadly virus in an attempt to prevent extinction of the human race. VC321xb47 kills fast and efficiently, shutting down the brain, and causes severe hemorrhages, which spreads the disease. The original virus weakens itself with each new host, dieing out after a certain number.…

    There has been a lot of controversy on whether or not viruses are considered alive. I believe that with a host cell, viruses are very much alive and are able to reproduce their genetics to further generations. Viruses are like babies so to speak, without the mother or the “host cell”, the baby is unable to live or grow. However, when the virus has not found its host cell, it’s in a dormant state with no internal activity, making it an invariable organic particle known as a ‘virion’ rather than a living organism.…

    There’s a long history of smallpox since it has been around for thousands of years. The European settlers first brought smallpox to North America in the 1600s. In 1633-1634, the disease swept through the Northeast, wiping out entire Native American tribes. Native populations in New England are thought to have plummeted by over 70 percent due to this outbreak (Mashantucket Pequot Museum and Research Center, 2012). Smallpox is spread when a person breathes it in and out.…

    Viruses cannot simply transmit themselves to one person at will. They need special genes to be able to unlock the cell and one of the specific hemagglutinin genes, also known as the key to the cell. Once it has the correct key, it diffuses its DNA with the cells, so it can then make more copies of itself. This gene is also referred to as H. Once the virus is able to make its copies, it faces another problem. The copies are not able to release themselves from their host cell.…

    This information is spread to the other cells. When the virus tries to invade a cell, a protein called cas-9 is activated and it reads the DNA looking for a match to the virus DNA it has in store. Once it finds a match, it targets that section of the DNA and cuts the virus replicating DNA out of the cell. The potential this has to cure human diseases is enormous.…
