T rex DNA

So how does bone marrow stay moist and intact for 70 million years in porous bone without either drying up, or becoming waterlogged from sitting in water...

bone up close looks like a sponge....

its either a miracle..or its not 70 million years old all I can figure..

Any scientists out there with ideas?

Who said it stays moist?

Go watch the movie Jurassic Park. It's possible to recover DNA that way but INCREDABLY unlikely to find! /ubbthreads/images/graemlins/grin.gif

If we do end up cloning one, one big cattle prod is going to be needed...

The DNA just needs to stay away from DNAase, enzymes that break it down. Well, then after that a few more "small" hurdles will have to be overcome before making a dinosaur. Although, if I had to wager, I'd say it'll be possible.

This is about the bignews story about finding MOIST bone marrow in a trex bone..

I guess you missed it..

I heard about this. I have no idea how it sayed intact for who-knows-how-long, but I hope they dont clone it. A pretty scary theory when I think of it... /ubbthreads/images/graemlins/aaa.gif But I am sure it is possible to clone it. If they can clone cats, mice, and sheep, they can probably clone Dinosaurs. After practicing on some birds first of course.

That is pretty interesting...

Oh yeah! Come on ... clone it! I want one!

Seems to me that I read that it was in a dry environment or the bone would have fossilized. Don't know about moist, but the marrow was flexible and speculation was that the unusually thick thigh bone of a T-Rex was what protected the marrow and that if museums were willing to cut up their displays they would likely find more of it. Also that they didn't think they would find more than DNA fragments, but I guess we'll know for sure when the first T-Rex escapes from the cloning factory /ubbthreads/images/graemlins/grin.gif

LEt's say for a moment that it was possible to clone it; where would they KEEP it? An airplane hangar? And if it's an omnivore, how could they afford to keep feeding it? I'm sure that it wouldn't be happy with Purina Dino Chow...

They'd keep it on an island and pay for the care and feeding by selling tickets to see it, of course /ubbthreads/images/graemlins/smile.gif

Then they would have the familiar electrical fences, then they have the guided tours that are cars with yellow and black stripes, and then, and then, why I already hear the theme song of Jurrassic park!

Unless the bones were buried 20 feet or deeper, continual bombardment by cosmic rays will have turned the DNA into mush.

You forgot to mention the.....MAXABEAMS!!!!!!!


(the electric trucks along the rail and the gas jeeps in the first JP were green, red, and yellow by the way /ubbthreads/images/graemlins/smile.gif .

In the second one they moved to heavily modified Mercedes M-class SUVs that wer gray/black)
