This is an easy to understand introduction to this famous question, nicely done! I lean more toward the opinion offered by one of my former professors: Life is a term for poets and philosophers, not scientists. The philosophical question is a fun one, but from a scientific point of view maybe we're better off focusing on the chemistry and evolution of replicators instead of trying to distill some list of traits that will cover the whole bunch. And viruses are certainly evolving replicators that undergo biological chemistry…

If your brain was somehow implanted with an instruction manual on how to make a copy of the instruction manual, and forces you to make so many copies of the instruction manual that you die of suffocating in instruction manuals what was alive? You or the instruction manual that you were forced to make copies of because all you could think about was making instruction manuals since it was implanted in your brain? The answer is, viruses, no matter what their state are not alive.

I'm afraid I don't see how your two-phase explanation answers the question. A cell is alive whether or not it's infected with a virus. The addition of virus particles doesn't make it any more or less alive (until the virus kills the cell). That doesn't really say anything about whether the virus is alive. You could just as well say that salt is not alive, but a cell containing salt is alive, so salt is a two-phase living organism. Which makes this concept far too broad to be a definition of what is alive, in my opinion.
@umblapag8 жыл бұрын
salt wouldn't be alive because it does not reproduce or evolve. when one says that a cell is alive, this presupposes that it has genetic material allowing it to evolve and reproduce. a virus infected cell enables a virus to do just that.
@troyjesse78334 жыл бұрын
I was thinking the same thing. Couldn't one argue that in the intracellular phase that the virus STILL isn't living, as it is the CELL that is providing all the necessary machinery and components for viral replication? The virus is essentially a piece of genetic material, and we certainly don't argue that DNA or RNA are alive just because they are found inside a cell. In the long run, it is really not an important question - viruses are important whether or not they are alive.
@ericlind65814 жыл бұрын
Umbert Lapagoss Perhaps salt isn’t the ideal example but his point is very valid. Just because it piggybacks onto something ALREADY living doesn’t mean it “becomes” alive cause many of the properties that define “life” are inherent to the cell itself and NOT the physical virus. the question of a virus infected cell being alive is NOT the same question as a Virus being alive.

Speaking as a professional armchair biologist I completely disagree, or rather I think the parameters for what constitutes "life" are arbitrary. Whether or not it has a cell, whether or not it makes energy, whether or not it grows, the means through which the virus produces more of itself or the means (or lack thereof) it has to interact with its environment are irrelevant as far as I'm concerned, the only thing that matters to me is can it reproduce and can it evolve, and the answer to those are yes, the fact that its method of doing so is as an obligate intercellular parasite is again, irrelevant. To my mind viruses are some of the simplest forms of life possible, and I spit on any trained professional who's studied the topic for years who disagrees with me. So there!

Life is a symphony, a party, a dance of different various molecules. A virus is alone, it doesn't do what cells do, it doesn't produce what cells produce. If you take a step back and try to realise, if you could hear the molecules of cells, a virus doesn't create this symphony or dance. Also cells have a baby stage and a mature stage, all living things do, living things breathe or exchange, inhale, exhale, or excreate, living things are uniquely reliant on water, require water in one way or another. Maybe start there. Instead of using linear thinking and what is only visible to define life.

Meaning it has encoded instructions capable of "generating" life after its kind in accordance with its embedded instructions. Most people ignore the obvious "thought/idea", because it makes some them think of their misguided beliefs about religion. The unfathomable idea that man is the only maker or creator of things. That everything man didn't make or create, could not have been made or created by a maker like him. They'd rather consider themselves to be an accidental non-random seguence of non-purposed events. Even when the simplest thing like a "virus" defies his ability to construct or determine if it is alive or not.

The first criteria you set for life is a non sequitur. By saying one or more, you encompass all cells, and a cell is just another word for box, cubicle, enclousre, and so on. the point about evolving is also subject to scrutiny in my book, because changing form doesn't require volition, as in consciousness. This happens to molecules all the time, and it's because of electricity. You could say that electrons are living beings by that criteria. How can you call it an organism when it doesn't meet any of your own criteria set for life? That's criminally negligent. It seems to me that cells eat these protein capsules for the protein, and then get dissolved, or not, by the acid, RNA, which is inside of the ... virus, exosome, particle, whatever you want to call these multituduous, if that's a word, particles, and that this only occurs if the acid inside of this semi-biotic thingy is potent enough to dissolve an entire cell. I don't think that drinking bleach is good for you, and, I, likewise, recognize that an alkaline environment in a living thing is more robust to tackle outside influence, as is proved by the fact that most plants are alkaline, and meats acidic - plants can withstand attacks from microorganisms to a much greater degree because of having a hard outer shell, and the ability to withdraw water and nutrition from soil, which is absolutely teeming with microorganisms.

Once it enters the cell, its genome does not encompass 99% of the infected cell's proteins, so your answer is abysmal in that viruses are obviously and permanently nonliving bimolecular constructs.

I don’t like this two-phased explanation cause a “virus infected cell” being alive is not the same thing as the physical virus itself being alive. that’s like asking is my severed head alive vs. my head when attached to my body. Two entirely different questions!

Jodi Goswellen Ok so follow me now. Common belief that is pushed by epidemiologists is they can live on surfaces for some period of time and thus these contaminated surfaces can infect humans that touch them. It seems shady science because I lived in NYC and took the subways everyday with hundreds of thousands of people from all walks of life and we hung onto poles and straps and were in close quarters of each other with some coughing and sneezing and never once was there a viral outbreak that would threaten the shutdown of the subway system with many people being falling ill or even the ill being on the train and not there being outbreaks in great numbers of influenza... Something not adding up

Let me add this fact my 2 grandsons had not been vaccinated until going to school as it is mandatory( our bodies should never be shot with forgein substances) they never were sick then they go to school and are sick for month's. So that is something to thonk about.

My issue with viruses is I have never seen actual convincing evidence that they exist. I would love to see some real science that demonstrates the existence of viruses. This video is nothing but theory. And what I find creepy is there is nothing on KZfaq about viruses that scientifically shows me that viruses are real.

In some ways whether something is alive is irrelevant. What matters is the practical issues-how it affects organisms. We can say a virus is a biological machine.

I really like your definition. So simple so deep. Drawing a distinction between VIRUS and "VIRUS INFECTED CELL". Would you like to comment on thinking of viruses as CELL'S MESSAGES? Therefore the argue of whether virus is alive of dead drop automatically.
