By what kind of mechanism does formalin inactivate the whole virus?

You're pretty much spot on WRT thepoteins. Formalin also causes DNA damage by both physically breaking the DNA strands and altering the tertiary structure.

Hello,\n\nHIV Virus, is a blood virus which when exposed to air weakens the virus in terms of tranferring the virus to another human being. and laos there has to be an open cut for transmission to be achieved.....\n\nIf you live with someone, who is hiv and they break a glass, as far as i know bleach can deactivate hiv. \n\nIf the blood is dried up it is not effective but don't use a syringe even though the blood has dried up fromsomeone else....\n\nAnything can happen....

A virus needs a cell to replicate itself. You see viruses have absolutely no ability to reproduce on there own. They basically "hijack" a cell and then the cell makes a copy of the virus.

Hi:\n\nMiller's experiment did just that... produced organic matter from inorganic matter, simulating the primitive conditions. What is believed to have happened after that is difficult to simulate as it was a random process of associations of the various organic compounds to form primitive complex structures, like say even catalytic RNA. This would have taken millions of years in itself and is difficult to reproduce in vitro.\n\nIf it is of some consolation to you, scientists have created a virus from scratch, about a year ago and the results were published in Nature.\n\nCheers!!

*claps* 3 people managed to say the exact same thing and STILL DIDN'T answer the question.\n\nYour asking how to remove a virus manualy from a computer, presumably you have already found it and the antivirus has said that it can not be removed.  This is probably because windows protects certian types of files from being accidently being deleted.  Your best bet is to reboot your computer into safe mode when it starts up, then run your virus scan again and it should be able to get rid of the virus.  To get into safe mode read this http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406?OpenDocument&src=sec_doc_nam\nIf that doesn't work, find the EXACT name of the virus and google it.  Usually Norton of Mcafee will have a information page about that particular virus and manual removal instructions which are usually quite longer than a reboot and try again.

I would have to guess that it involves the neutralization reaction of more than 2 substances.\n\nJust a guess

911, a virus stays in the body. It does not go away and cannot be cured, only controlled.

This is a guess, especially because I don't know what the diluent is made of, but maybe its because the viral coat is weaker and more susceptible to bursting without some sort of albumin present?\n\nGood luck.

Instead of going on and on like most people who commented here,I will provide you a simple answer to your question.\nHow do you kill a virus or any type of disease? Same principle here.You must systematically,completely,and totally obliterate it from the host.A long and expensive proposition,I know.I'll make anyone who's listening out there a deal;\nif you or your organization will pay for it,my team and I will get started.Try me...

it's important to maintain a certain concentration level of the antibiotic in order to kill the bacteria if you stop the antibiotic it just won't be able to work the next time you need it cause the bacteria is resistant to it. and a vaccine is usually inactivated virus and when they get into your body your body developes antibodies and when you get an active virus the antibodies will fight it

Purify it. And then have it in a closed system where nothing can get to it

Ok if u kept ur computer box and its not too old, ther MIGHT be a disk in ther that erases EVERYTHING. its a recovery disk and itll get the virus off BUT you have to reinstalll Everything and start over from scratch. If u cant find it call the computers maker and tell them ur model and everything they ask and theyll send u a disk in the mail. Fo some money though. PS. I HAD TO DO THIS BUT IT WASENT THAT BIG OF DEAL WITH MY COMPUTER. GOOD LUCK

There's also cell apoptosis.  infected cells put out a self-destruct signal so the virus can't reproduce.  its actually what i work on, with herpes

YES.....if for example u are in contact with the virus.....it cannot be washed off with water....u gotta use soap also........or if u want to disinfect it in some food item....cook it or heat it at more than 70 degree CELSIUS for some seconds b4 consuming.....

No, they use the entire machinery of the host cell to do that.Viruses do not have their own enzymes.

Hydrogen and Nitrogen I THINK.  Not 100% on that one\nUpdate***\nA friend has suggested that it might also be full chemical name of the virus, though I don't know what that is.  His answer seems to be a more complete one, and given that he is a chemist... far more likely.

The answers to these questions would be specific to whatever virus you are interested in looking at. Some viruses can be cultured, some cannot. Immunofluorescence requires that you have an antibody that is specific for the virus you are trying to detect
