i think when DNA or RNA of virus get entry into the host, afterwards old virus do not remain alive, and DNA or RNA directs the synthesis of new viruses.

That's right, stones can divide themselves as well ;)

Cis or trans? That's what matters.

Mith: think out side of the box....I know a textbook will tell you that viruses aren't considered life....but that is just B.S., Viruses are just a different form of life....but nevertheless, they are living.

For example when Robert Hooke came up with a template stating that all living organisms contain particular traits, for example, they all metabolize...he was just making up these guidelines while using his primitive microscope.

Now that we have electron microscopes we are able to see a lot smaller things, and it turns out we found an organism (viruses) that don't fit all the guidelines that hooke designed a LONG TIME AGO, and since viruses don't metabolize on their own, people automatically assume it isn't life ...but it is, they are a form of life...they just don't fit under the categories someone made in the late 1600's. But that is ok, the knowledge of science grows through out the years.

Yea I said it....I am challenging the text books.

then can we say that any thing having nuclear material like DNA or RNA is living

i do not know but then if we come to see of this as darwin420 says then we will have to change everything. the whole system.
who fears it. but then the basics of everything will be shaken
but i also think a virus can also be called alive. don't we call different organisms that go into hibernation alive??? so why not viruses. they go into longer hibernations until their surroundings suit them.
muzna has got a good point that slipped off my head.
but i still wonder can they becalled dead after they enter the cells. its justa method of division in which many jwalin's will be producedfrom one jwalin ( that's an example) i would prefer to call it something else i am confused???
why not call even the mitochondrias living? what about ribosomes?
i do not know the original or the exact definition of the " living organism "
help would be appreciated
if i offend someone i am sorry.
it isn't what you do that matters but it is how you do it

are cells referred to as dead after they divide.
i think not then iwas right. else wrong.
please tell me if i am right or wrong.

no, and they're not referred as dead.

@darwin420, and everyone else too
Remember that living and non-living are just words, they don't impact nature at all. if you consider viruses as non-living or a different type of life, they're still the same thing. These are human conventions, so by all means consider them whatever they want. But remember that this whole living-nonliving stuff is just philosophical BS, not science, and therefore does not make any difference.
