Is it possible to bring back dinosaurs?

Question

Could we bring dinosaurs back to life using their DNA??? If yes could we possibly do it with other extinct animals we have DNA of??? I'd really like to know, not that I think bringing back a T-rex is such a good idea.

Answer 1

No. We've only ever found dinosaur DNA in one sample, and it's too fragmented and damaged to bring a dinosaur back with. We're just talking far too long ago for any DNA to be intact/usable.

Bringing back recently extinct animals - at least, recently enough to have their DNA relatively undamaged - is a possibility though. Scientists are planning to bring back the quagga (a kind of stripy horse, like a zebra) that went extinct in the 19th century, and there is even talk of bringing back the mammoth.

Answer 2

Finding complete DNA, as other answerers have mentioned, is the primary problem. Higher organisms have many thousands of genes (humans have 27,000), which would need to be in almost pristine condtion to produce a clone. There is, of course, another issue beyond finding complete DNA strands (which is more or less almost impossible).  

Which is - How would we clone it? Informally, we can think of cloning as needing a "mechanism" (the DNA) and the "machinery" (an organism to produce the clone). If you cast your mind back to Dolly the sheep, we were able to produce the clone Dolly because we had the DNA and another sheep to allow the embryo to grow.

This isn't the case with dinosaurs. Even if we did have the DNA to produce a clone, we would need something to incubate the egg. And of course, since the last dinosaurs died 65 million years ago, this is a bit of an issue.

While it is possible to bring back extinct animals, it is only really feasible (with modern technology) if there is a suitably close relative of the extinct species still alive, which is the case with the quagga (horse / zebra) and potentially even a mammoth (it is speculated that an elephant may have the ability to grow a mammoth embryo in it's womb).

Answer 3

It is not possible to bring back dinosaurs from there DNA. Although scientists have found tissue remains inside the bones of dinosaurs, the DNA inside the tissue is probably too damaged to read and if you can't read it, then you can't clone a dinosaur. But there is no need to bring them back seeing as how they never went extinct. After all, birds are the direct descendants of coelurosaurs. As for making a T-rex, well you can continue to alter the DNA of modern day birds until start to look like T-rex, but it would be classified as a genetically engineered bird, not T-rex. Theres a program on discovery channel called Dinosaurs Return to Life where they are attempting to retro-engineer birds to look like dinosaurs. I'm pretty sure some one would have bootlegged it by now on the internet. You should check it out.

Answer 4

we can't.if we could we would have done it by now.

there is no use.people should spend a lot of money on that.
