Today’s blog is an interesting one as it is on the Dinosaurs and I hope the Dino fans would enjoy it . Here an Interesting question is raised whether we can clone a Dinosaur’s DNA or not ?. So now learn it from the blog and hope you guys have fun after reading it.

Apologies to the people keen on reviving extinct Dinosaurs, but researchers have never recovered dinosaur DNA, which is vital for cloning. But, interestingly, they have discovered sections of secret DNA in dinosaur bone, specialists told .
It’s obscure whether this DNA is dinosaurian, or whether it has a place with other life-forms, for example, organisms; nondinosaurian creatures, for example, earthworms; or even paleontologists who have worked with these fossils.
It’s no surprise that dinosaur remains contain DNA. Bone is somewhat comprised of a mineral called hydroxyapatite, which has a solid affinity for certain biomolecules, including DNA. In fact, specialists frequently utilize hydroxyapatite to purify and concentrate DNA in the lab, a researcher told.
Scientists need DNA to clone dinosaurs, but an organism’s DNA starts decaying the moment after that organism dies .
That is because enzymes (from soil organisms, body cells and gut cells) degrade DNA. So does UV radiation. Besides, Oxygen and water can alter the DNA, creating the strands to break and “These things will separate the DNA into smaller and more degraded pieces, until in the end, there is nothing left,” said a researcher.

If any DNA from the Mesozoic period has miraculously survived, then it would likely be fragmented and badly damaged, making it unsuitable for use in cloning dinosaurs.
The research says that the oldest recovered and authenticated DNA from bone belongs to a 700,000-year old horse from the solidified Klondike gold fields in Yukon, Canada.
The DNA fragments that were recovered from that horse bone were short (on average 40-ish letters long) and showed characteristic signs of postmortem damage. But they could be mapped to the genome of a modern horse, and so we know that they were of horse origin.
Interestingly, the dinosaurs’ living relatives are flying creatures. Be that as it may, winged creatures advanced out of the theropod line — a gathering of bipedal, generally savage dinosaurs, for example, Tyrannosaurus rex and Velocipede. Other dinosaur bunches — including the hadrosaurs (the duck-charged dinosaurs), the triceratops, the stegosaurus and the ankylosaurs — don’t have living relatives.
For contention, suppose that scientists discovered completely sequenced dinosaur DNA. This implies specialists would have a whole genome, including the purported junk DNA and the viral DNA that is joined itself into the dinosaur’s hereditary code. This viral DNA could be an issue, particularly in the event that it could infect modern plants and creatures.
It would take about 5,000 Velociraptors (or any dinosaur species, for that matter) to make a sustainable population with genetic diversity.
There are so many problems researchers would have to overcome to clone a dinosaur like the creature’s digestive enzymes might not work on modern animals and plants, and it wouldn’t have Mesozoic microbes, which it likely would need to digest and absorb nutrients.
But to be honest I would like to see a T.rex,it would be very cool.
