The recipe for making any creature is wriitten in its DNA. If so,then its very much possible to regenerate an extincted organism from its DNA (when the complete DNA sequence of that organism is known).
Creating a living, breathing creature from a genome sequence that exists only in a computer's memory is not possible right now. But someone someday is sure to try it, predicts Stephan Schuster, a molecular biologist at Pennsylvania State University. It is only going to be possible with creatures for which we can retrieve a complete genome sequence. Without this, there is no chance,he added.
Usually when a creature dies, the DNA in any flesh left untouched is soon destroyed as it is attacked by sunshine and bacteria.There are, however, some circumstances in which DNA can be preserved. If your specimen froze to death in an icy wasteland such as Siberia, or snuffed it in a dark cave or a really dry region, for instance, then the probability of finding some intact stretches of DNA is much higher.
The genomes of several extinct species are already being sequenced, but turning these into living creatures will not be easy . "It's hard to say that something will never ever be possible," says Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, "but it would require technologies so far removed from what we currently have that I cannot imagine how it would be done."
But 50 years ago, who would have believed we would now be able to read the instructions for making humans, fix inherited diseases, clone mammals and be close to creating artificial life?
So, its for sure , oneday something like this will be done !!!
Its all about the fascinating science of Genetic Engineering and no one knows where to stop thinking !!!
