Paolo Fril, chairman and scientific officer of GeneDupe, based in San Melito, California, is a man with a dream. The dream is a dragon in every home.
GeneDupe’s business is biotech pets. Not for Dr. Fril, though, the cloning of dead cats and dogs. He plans a range of entirely new animals—or, rather, of really quite old animals, with the twist that when they did exist, it was only in the imagination.
Making a mythical creature real is not easy. But GeneDupe’s team of biologists and computer scientists reckon they are equal to the task. Their secret is a new field, which they call "virtual cell biology".
Biology and computing have a lot in common, since both are about processing information—in one case electronic: in the other, biochemical. Virtual cell biology aspires to make a software model of a cell that is accurate in every biochemical detail. That is possible because all animal cells use the same parts list—mitochondria for energy processing, the endoplasmic reticulum for making proteins , Golgi body for protein assembly, and so on.
Armed with their virtual cell, GeneDupe’s scientists can customize the result so that it belongs to a particular species, by loading it with a virtual copy of that animal’s genome. Then, if the cell is also loaded with the right virtual molecules, it will behave like a fertilized egg, and start dividing and developing—first into embryo, and ultimately into an adult.
Because this "growth" is going on in a computer, it happens fast. Passing from egg to adult in one of GeneDupe’s enormous Mythmaker computers takes less than a minute. And it is here that Charles Darwin gets a look in. With such a short generation time, GeneDupe’s scientists can add a little evolution to their products.
Each computer starts with a search image(dragon, unicorn, griffin, etc), and the genome of the real animal most closely resembling it(a lizard for the dragon, a horse for the unicorn and most taxingly, the spliced genomes of a lion and an eagle for the griffin). The virtual genomes of these real animals are then tweaked by random electronic mutations. When they have matured, the virtual adults most closely resembling the targets are picked and cross-bred, while the others are culled.
Using this rapid evolutionary process, GeneDupe’s scientists have arrived at genomes for a range of mythological creatures—-in a computer, at least. The next stage, on which they are just embarking, is to do it for real.
This involves synthesizing, with actual DNA, the genetic material that the computer models predict will produce the mythical creatures. The synthetic DNA is then inserted into a cell that has had its natural nucleus removed. The result, Dr. Fril and his commercial backers hope, will be a real live dragon, unicorn or what you have. Dr. Fril is confident about his new idea. Indeed, if he can get the dragon’s respiration correct, he thinks they will set the world on fire.
The team has chosen a lizard for the dragon as they think these creatures
选项
A、have the same genome.
B、have similar appearances.
C、belong to the same species.
D、possess the same genetic structure.
答案
B
解析
推断题。题日问的是“这个团队为龙选择蜥蜴是因为这些生物 。”根据第七段的“Each computer starts with asearch image(dragon,unicorn,griffin,etc),and the genome ofthe real animal most closely resembling it(a lizard for the dragon,a horse for the unicorn and most taxingly,the spliced genomes of alion and an eagle for the griffin).”可知,每台计算机开始于搜索形象(龙)和与这种形象最相似的真实动物的基因组(与龙相似的蜥蜴)。故选B。
