Viruses appear to have functions, different in nature, but comparable in complexity to bacteria are viruses alive are viruses sentient. Chickenpox and ____________ are caused by the same virus a) viruses are not alive because they lack some of the key characteristics of living organisms, such as a cytoplasm of organelles they cannot carry out cellular functions such as metabolism and homeostasis.
For your first question, whether viruses are alive, viruses are not generally considered to be alive, although a lot of debate surrounds this question if you look at a tree that shows all living organisms on it, you will not find viruses there. While the answer below is creative and can somewhat be understood, the simple answer to this question is: no a computer virus is not alive it is just a malevolent program that is designed to automatically attack a computer, but it is not alive like viruses that attack a human body. Which argument supports the idea that viruses are alive viruses have a cell membrane viruses contain unique genetic information viruses replicate in a - 507572.
Viruses are assembles of organic molecules that consist of some short strands of rna or dna encapsulated within a protein shell they are often referred to as if they were living organisms, but they don't meet the criteria listed above for living things. Viruses are right on the border of being alive and non living viruses are consider non-living as they can not reproduce on their own they must invade a host cell, inject it's dna into the dna of the host cell, making the host cell a virus factory. The discovery of a giant virus that falls ill through infection by another virus 1 is fuelling the debate about whether viruses are alive “there’s no doubt this is a living organism,” says jean-michel claverie, a virologist at the the cnrs upr laboratories in marseilles, part of france’s. Viruses are infectious, tiny and nasty but are they alive not really, although it depends on what your definition of alive is, two infectious disease doctors told live science living beings, such as plants and animals, contain cellular machinery that allows them to self-replicate in contrast.
Chances are that you have been infected by a virus, whether it be the common cold or chicken pox or one of the many others viruses are common, but there are more to them than they appear they are more difficult to treat because antibiotics cannot be used against them the reason for this is that. A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report the study offers the first reliable method for tracing viral evolution back to. Viruses are not considered alive because they lack many of the properties that scientists associate with living organisms primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell- division approach to replication.
Their diversity makes viruses difficult to classify a new study uses protein folds as evidence that viruses are living entities that belong on their own branch of the tree of life. Viruses have weirded us out since they were first discovered over a century ago, but are these microscopic protein pirates alive you bet, if you're prepared to think outside the box. Are viruses alive if asking questions you don’t like is spouting dogma crawford then tough.
Viruses are unique in that they have been classified as both living and nonliving at various times learn about virus structure and viral disease. Viruses are alive, and they’re older than modern cells, new study suggests arshan nasir, who is caetano-anollés' graduate student and also worked on the study, added that "viruses are living. Instead, viruses enter living cells and then hijack the host’s cellular equipment to copy viral genetic information, build new capsids, and assemble everything together we use the term replicate, instead of reproduce, to indicate viruses need a host cell to multiply. Giant viruses are ancient living organisms camilli even found that viruses acquire their own immune systems he said that once viruses that attack bacteria capture an immune system, they can then disarm the host cell, and can then proceed with the infection and kill the host cell.
In my opinion i think that viruses are alive viruses contain some characteristics of life in them such as reproduction, dna or rna some may disagree that viruses are not alive viruses don’t have cellular machinery it must use the host’s in order to make copies of itself viruses only exist to make more of themselves. Viruses by themselves are not alive they cannot grow or multiply on their own and need to enter a human or animal cell and take over the cell to help them multiply these viruses may also infect bacterial cells. Viruses are very small particles that can infect animals and plants and make them sick viruses are made up of genetic materials like dna and are protected by a coating of protein viruses hijack the cells of living organisms they inject their genetic material right into the cell and take over. Viruses are microscopic parasites that lack suggested that the cause of tobacco mosaic disease was not bacterial but a “living liquid virus,” referring to.Download
