Here be dragons

GeneDupe's business is biotech pets. Not for Dr Fril, though, the mundane cloning of dead moggies and pooches. He plans a range of entirely new animals—or, rather, of really quite old animals, with the twist that even when they did exist, it was only in the imagination.

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.

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.

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 synthesising, 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 have you.
