No 'Jurassic Park' for you! DNA has a half-life of 521 years
A group of scientists from New Zealand and Australia have officially busted the myth on cloning dinosaurs, along with the whole idea of real-life Jurassic Park. As it turns out, DNA has a half-life of only 521 years—completely ruling out the possibility of cloning the last dinosaurs that died 65 million years ago.
As CNET relays, the scientist tested the viability of DNA by taking samples from 158 leg bones from moa birds that died out between 600 to 8,000 years ago. The scientists compared the degradation of the strands and came to the conclusion that DNA’s nucleotide bonds (the chains linking our DNA strands) break down too quickly to bring the dinosaurs back to life.
In this particular experiment, scientists from the University of Copenhagen and Murdoch University examined leg bones from three different sites with similar preservation conditions. All of the sites were swamps with a temperature of 13.1 degrees Celsius (around 56 degrees Fahrenheit).
The scientists, however, say that even with the ideal preservation temperature of -5 degrees Celsius (23 degrees Fahrenheit), a DNA sample would only last for 1.5 million years. So if you're planning on getting cloned anytime in the near future you may want to look into cryogenic freezing.
