What are some biological problems in Jurassic Park?

1993 Jurassic Park was at the time of its release of the highest film in the world, earning revenues of over $ 914 million (US dollars). The prerequisite for the film is that scientists were able to revive dinosaurs by getting their DNA from the intestine of ancient mosquitoes preserved in amber. DNA DINOSAUR Fragments are amplified by PCR (polymerase chain reaction), gaps are filled with frog DNA and the repaired genome is then injected into an ostrich egg and brought to the artificial womb. Since the film was released, curious people asked, "Could it really be possible?"

Often, when the biologist is asked to the feasibility of Jurassic Park , they get intellectually stuck on one of the numerous scientific inaccuracies in the Dinosaur revival scheme, and it will reject the possibility as a justification. Despite these inaccuracies, there is a considerable chance that the recovery of dinosaurs could really be possible, even if it would necessarily include progressClean biotechnology - biotechnology for decades more advanced than today. Biotechnological progress between 1993 and today has caused some of the earlier doubts to think twice before condemning the possibility.

There are many cases of fictional shine in the biotechnological scenario. Let's separate the truth from fiction. First, the isolation of ancient DNA from long dead organisms captured in amber is quite possible. However, there is a great disagreement about whether authentic DNA from samples can be recovered for more than about a million years. At the beginning of the 90s, it was reported that ancient DNA was obtained from unscrupulous bees, termites, Weevil, one dinosaur, plants, and bacteria dating up to 80 million years old of the chalk era. Unfortunately, a later critical overview found that these claims were very weak and that in addition to two highly controversialCHP 300 million years old DNA bacterial regeneration from rock salt is unlikely that DNA has been successfully recovered and reinforced. DNA dinosaur has proved to be human chromosome, introduced into a sample through contamination.

There is still a big disagreement about whether recovery of truly ancient DNA is possible. Whether it is or not, it was confirmed that the newer DNA, including DNA from Neanderthals and Mammots, was indeed obtained. However, there are other problems with the Jurassic Park scenario. Filling the gaps in the DNA Dinosaur with the frog DNA is likely to be very difficult if possible. One would have to know which frogs are dinosaurs' homologists that would probably require a huge amount of DNA DNA fragments and data sequencing. Enter incorrect genes and the animal may not even grow around the embryo stage.

The third main challenge with the access of Jurassic Park is to obtain a suitable egg for artificial dinosaurus gamete in which it is injected. Ostrich eggs would not worklo. Instead, an egg would be required of exactly the same kind. This could theoretically be synthesized from the original genetic material, but it would be difficult. This challenge is not solved in Jurassic Park - instead it is shiny.

If three main challenges (DNA recovery, genome, synthetic eggs of the same kind can be overcome), then the Jurassic Park scenario could be in real life. Until then, science will continue as always. In any case, it is much more likely that the recently extinct species, such as Mammoths and Neanderthals, will be revived by Befruda of any dinosaurs.
