Does Virii or has Virus Undergone any sort of Evolution?

:confused: :confused: :confused: :confused: :confused: :confused:

bye!

Yes, all the time! Viruses mutate very quickly and often, i believe. They take up DNA from their surroundings, mutate after each successive mitotic division...

Other members can go more in detail i think

Single stranded RNA virii like HIV mutate very fast because of the lest stable nature of ssRNA.

mutations are basically changes that take place in the genetic information.
Every organism is subject to mutation, because DNA is not 100% stable. There are some mechanism that repair damaged DNA, but once again, this system is not 100% perfect.

Evolution acts on genetic variation. And since everything that contains DNA or RNA mutates, they also are under the influence of evolution. A virus contains DNA or RNA. Viruses don't even have repair mechanisms (as far as i know of), therefore they are certainly subject to mutation. Hence they can evolve.

all above answers are to-the-point-good .

Virii (should be Virii over Viruses but it sounds weired though) don't live very long out side of host because exposure to sunlight (UV) shreds their genetics! Bacteria can live longer because they have repair mechanism like Thyamine diemer repair (common mutation cause by UV light).

“A virus is like a chain letter in a bottle”

thymine dimmers are pretty neat, eh? :)

No I'm relatively sure I spelled it right. :rolleyes:

:bugeye: eh....maybe there's more than one way to spell the little buggers, but, i was under the impression that they are spelled: Dimmers. no biggie...they are still pretty neat little excisors...that was my point. nothing like having a "pair of scissors" in our genetic make-up....ready to cut and past mistakes.

Its fine... I don't want to sound like a @$$ so I will just say what you said is "correct" in a vague but aaaah reasonable way :o

Its still deimer, i'm talking about something else you said.

:confused: :bugeye: :D you are off your goose!:D

??? :confused: :)

You guys are both off your respective rockers...it's dimer. As in monomer, dimer, trimer, tetramer, etc.

Not according to this Organic chem. book I got here!

So my biochemistry textbook is lying?

textbooks often contain semi-truths

diemer is a deimer is a dimer... jess lets leave it be it like asking who to pronounce "poison"

sorry to have to say this, but, it's you guys who are full of the proverbial shit. my micro bio books spells it dimmer, 'smatter of fact, so do all the RPH.'s here at work of which i asked their opinions on the this matter. oh, brother....just let's drop it. i think you males in this forum have a problem that i am a female who might just know a tad bit more about bio than you!:p :D

FEMINAZI!!!

One more point, and then I'll drop it.

I'll use a different example to explain. We call carbon monoxide what we do, because there is one oxygen. Mono = 1. We call carbon dioxide what we do because it has 2 oxygens. Di = 2.

When we have one thymine, it's a monomer. When we have 2, it's a dimer. Where are these "e's" and extra "m's" coming from?

I'm done.

From who ever spell checks these books of course!

maybe it is old school spelling

That is amazing...you had a discussion on this?Its Dimer off course...,You know Poly-Mer,Di-mer ...are you guys in College...

sorry if that offends...?!?



bye!

no...went past the college phase...and am now in the phase "nothing suprises me anymore"

OOPs...

bye!

I just asked 3 college chemistry professors and I got:
Dr. Dvorak: "Dimer"
Dr. Sherrama: "Dimmer"
Dr. Gregory: "Dimmer"

dude! awesome!!! that means we are ALL right ..think about the implications of that! :D wwwwwwwwwwoooooooo


:D and, i just wanted to let all you guys know i love you with all (well, most) of my heart. :D seriously...i love(but, don't get all carried away) all the people that post on this message board. they are pretty a-ok. lotsa love here...can't you feel it?

now, onto the "dimers" ..ahem.. did you know there are other kinds...:D :p for example: pyrimidine dimer (which is my personal favorite) :D


gots to go. *kisses and hugs to all you science geeks*

In English when you have something end with a "s" and your referring to it as many (plural) ... then it is expectable to change the ending to "i"

Such as

"Look at those fetuses." would be better preferred as "Look at those fetii."

or

"The radiuses of all 4 types of USA coins are?” wound be preferable change to “The radii of all 4 types of USA coins are?”

This is what happens what you listen to your stepmother that happens to be an editor.

That statement would make more sense if it started out with, "In Latin..." In English, most people expect plurals to end in S. It's only smart-ass college graduates like us that make up plurals like "Kleenices" and "Hippopotamodes."

Watch those double I's. "Radius" has an I, so the plural has two. If the singular just ends in US with no I, then the plural ending is just one I. Even if we used the Latin plural for "fetus," it is still "feti", not "fetii". "Fetii" would be the plural of "fetius", whatever that is.

My favorite was coined by a professor: If the plural of "opus" is "opera," then the plural of "walrus" must be "walrera"!

thx for correcting my spelling... I'm not a good speller by the way ;) I don't see anything wrong with the "i" back to the main subject then.
