2011年7月10日 · This innate conservatism of DNA emboldened Wu to use whatever DNA he wished. In making his dinosaurs, Wu had manipulated the DNA as a sculptor might clay or marble. He had created freely. [Wu runs a computer search for Rana DNA among the dinosaurs.] The result was clear: all breeding dinosaurs incorporated rana, or frog, DNA. None of the other ...

2023年4月10日 · Well, on the tour, the film said they used frog DNA to fill in the gene sequence gaps. They mutated the dinosaurs' genetic code and blended it with that of frogs. Some species of West African frog are known to spontaneously change sex from male to female in a single-sex environment. [chuckles a bit] Malcolm was right. Look.

2016年6月14日 · Their only dino DNA source was blood from the stomachs of mosquitoes found in amber that fossilized when dinosaurs still lived, correct? Let's suppose that it is possible to use that DNA as a foundation and "fill in the blanks" using modern frog DNA.

2021年12月9日 · In the novel Jurassic Park, Michael Crichton makes the point that frog DNA was used to fill gaps in the genetic code where genuine dino DNA was missing. As an unintended consequence, the dinosaurs proved able to change sex under some circumstances, as happens with some living frogs.

The characters in the novel (as well as the readers, especially readers in 1990) have no idea what real dinosaurs were like. They have skeletons and footprints and coprolites, but they don't have an original to compare their creations to. They can't know what features of the clones are "correct," and what features were introduced by frog DNA.

They replaced missing DNA with DNA of a frog. Also, only a handful of species were presented in the film; it would be foolish to assume that they had cloned more than 30 or 40 species. And as others have pointed out, they likely had quite a volume of amber pieces. There is another point: DNA similarities among similar species is staggeringly high.

2016年1月26日 · IIRC there was (at least in the book) a mock-explanation based on Jurassic Park's use of amphibian DNA, as apparently with toads and frogs vision is based largely on detection of movement (not that I actually know anything about frogs, or find that explanation in any way believable). –

2018年8月10日 · It turns out that the vulnerability from the frog's DNA was probably built in intentionally and she gets saved by injecting a specific frog virus delivered to the IIS by her almost-ex-husband. Earlier in the story though, one of the other protagonists tries to return home uninfected but gets destroyed by the military though.

2015年10月21日 · @Jon of All Trades - The reason I didn't post it as an answer is that Lego Stormtroopr seems to be looking for an in-universe answer, my comment was mainly about the out-of-universe reason, I did offer the idea that a reader could imagine that Gregory S. Paul's suggestion was accepted by paleontologists in the alternate universe of Jurassic Park, but I don't think Paul is actually mentioned ...

2023年9月21日 · notes: i'm calling this the 'common cold of genetics'. we can't cure this one soon i'm sure. because we're actively manipulating and mutating the animals' genes, adding frog, bird and reptile dna, we create what is known as 'null allele'. the dinosaurs cannot live without something added to their code so for now we're stuck with scales.
