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.
Dr. Fril and his team think they will succeed
选项
A、with the advancement of computer sciences.
B、as they have worked out genomes by computer.
C、when they find the actual DNA.
D、if they get enough commercial backers.
答案
C
解析
推断题。题目问的是“福瑞尔博士和他的团队认为他们将会成功 。”根据第八段“Using this rapid evolutionaryprocess,GeneDupe’s scientists have arrived at genomes for a rangeof mythological creatures--in a computer,at least.The next stage,on which they are just embarking,is to do it for real.”可知,通过这种快速进化过程,基因复制公司的科学家们至少已经在计算机中完成了一系列神话生物的基因组,下一步,也是他们刚刚着手的工作,就是把它们变成现实。由最后一段的“This involvessynthesizing,with actual DNA,the genetic material that the com—puter models predict will produce the mythical creatures.”和“Dr.Fril is confident about his new idea.Indeed,if he can get thedragon’s respiration correct.he thinks they will set the world onfire.”可知,这涉及到实际DNA和计算机模型预测会产生神话生物的遗传物质的合成,如果取得实际DNA,他们就可以取得成功。B选项是他们已在计算机上完成基因组,并不能完全符合合成的要求。故选C。
