Man vs nature : Can man harness or change nature? Describe a real life example and give your opinion of it. This means that your body needs lysine for proper healthy functions, such as building proteins, absorbing calcium for bone growth, and lowering cholesterol. However, your body does not make lysine on its own, thus it is essential that humans get lysine from their diet, by eating lysine-rich foods, such as beans, meat, eggs, and cheese.
In Jurassic Park , the dinosaurs are engineered to not produce lysine as a precautionary measure so that the dinosaurs could not survive if they ever found their way off the island. However, Jurassic Park sequels illustrate that the dinosaurs find their way around this contingency by eating plants or other smaller dinosaurs to get this amino acid anyway.
In reality, vertebrates do not even produce lysine and it is unlikely that dinosaurs would have need ed this genetic alteration in the first place. As the egg shell shows the first signs of hatching, Dr.
Henry Wu mentions that all the dinosaurs in Jurassic Park were specifically designed to be female to prevent any unauthorized dinosaur breeding outside of the lab. He claims that all vertebrate embryos are female to begin with, then just require an additional hormone to become male, which Jurassic Park scientists prevent.
This aspect of developmental biology is actually still a current source of debate. When Dr. Grant and the children get lost in Jurassic Park after the T. Grant then remembers that they filled the holes in the dinosaur DNA with DNA from a frog and that some frog species from West Africa can change sex in single-sex environments. This sex-change mechanism exists to ensure the survival of the species, if one sex ends up being eliminated or in short supply.
In the s, a study was published that suggested the Common reed frog, Hyperolius viridiflavus, from West Africa could change sex from female to male. However, the process of changing sex, which has been observed in many animals such as frogs, snakes, slugs, and fish, involves a number of different molecular mechanisms and environmental factors. One would need to know which frog genes are homologous with which dinosaur genes, which would likely require a huge amount of dinosaur DNA fragments and sequencing data.
Input the wrong genes, and the animal might not even grow past the embryo stage. The third major challenge with the Jurassic Park approach is getting a suitable egg for the artificial dinosaur gamete to be injected into.
An ostrich egg would not work. Instead, an egg of the exact same species would be required. This could theoretically be synthesized from the original genetic material, but it would be difficult.
This challenge is not addressed in Jurassic Park -- instead it is glossed over. If the three main challenges listed recovery of DNA, repairing the genome, synthetic egg of the same species can be overcome, then a Jurassic Park scenario could become possible in real life.
Until then, science will go on as always. In any case, it's far more likely that recently extinct species, such as mammoths and Neanderthals, will be revived before any dinosaurs.
