Is it possible to Clone a Dinosaur ?

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.

Introduction

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.

How Long can a DNA survive ?

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.

Dinosaur DNA ?

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.

Cloning Adventures

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.

    Hi,
    I really liked the topic of this blog, I mean who wouldn’t love the idea of dinosaurs returning! I like your optimism.
    I just wanted to know how you feel about the ethical issues revolved around cloning something as controversial as dinosaurs?. Cloning is a really controversial issue for a number of reasons. One being the success rate of it is extremely low because its so easy for the genetic information to get damaged in the process. So this means that even if enough dinosaur DNA was collected, a lot of time and resources will be used up and unfortunately nothing could even come out of it! Frustrating i know!. So cloning one dinosaur would be near impossible let alone 5,000.
    (http://www.bioethics.org.au/Resources/Resource%20Topics/Cloning.html)
    so what are your thoughts about the ethical issues behind it?
    l really enjoyed reading your post, great job!

    I really enjoyed this post, even though it doesn’t leave much hope to see dinosaurs in this day and age.I noticed at the end of the blog that you focused on the issues that the cloned diosaur could potentially have with it’s surroundings, and didn’t mention the effect that it could have to it’s surroundings, such as those shown on Jurassic Park for example (not a very legitimate example but it does have some points missed in this blog) especially considering the place that it would hold in the food chain (of course if it is able to eat), the Lion would definitely not be the king of the jungle anymore. There was also something that I found to be quite confusing, when you mentioned the relations that dinosaurs currently have with winged creatures now you gave T-rex as an answer, however, later when listing the dinosaurs with no living relatives you also listed Tyrannosaurs. After a few times re-reading it i believe you were just trying to give examples of the creatures that you generalised. It would hvae been helpful if you had said instead that the bird creatures today may come from Sinosauropteryx, Unenlagia and Oviraptor, and had links to what they are. I found this information from this website:http://www.abc.net.au/science/slab/dinobird/story.htm
    Thank you for sharing your insight.

    Hi there,
    I enjoyed your post on disusing the possibility of cloning dinosaurs. For the part discussing how long the DNA can survive, here are some facts to support. According to Kaplan, researchers found that DNA has 521-year half-life. Everything in the environment after a cell death speeds up the decaying of the elements in that organism; nucleotide bonds will be broken down by enzymes and micro-organisms speeds up the decaying of cells. Therefore it is quite difficult to recover a perfect DNA if it is discovered in a long time after their death.

    If DNA is able to recover miraculously, I’d also hope that dinosaurs can exist in our world today.
