Reasons some say viruses are not alive: They have no cells (only protein coatings surrounding genetic material). They don't reproduce by themselves; they need host cells. And one thing still undecided—do viruses respond to their environment? It's hard to say. Some argue that they do not,...
When cells recognize viruses and gene mutations, they may induce death to prevent the damage from spreading. When cells are under stress, as may happen when free radicals are on the loose or when a person undergoes radiation, apoptosis can occur. But there are also signals within the body ...

You probably didn’t know that Viruses make up most of the DNA on our planet. There are more viruses on earth than there are stars in the universe. That’s a really, really, REALLY big number. Viruses inject their DNA into their hosts, thus preserving their DNA and allowing it to repl...
