It says

"In this new organism, the number of genes can only be pared down to 473, 149 of which have functions that are completely unknown."

But if we now can simulate this cell completely, shouldn't it be easy to figure out what those genes are doing? Just start the simulation with them knocked out.




Presumably if the number of genes cannot be pared down below 473, it dies very quickly if one of the 149 genes is knocked out. But "it doesn't work without it" is not a very satisfactory answer to "what does it do".


Yes, this is similar to opening a radio and saying "I don't know what this transistor does; let's take it out and see what the radio does".

The funny thing is if you read the history of Feynman and others, most of them grew up opening up radios and learning how they worked by removing things. fixing them. It's a very common theme (sort of falls off post-transistor tho). I opened up radios as a kid, tried to figure out what parts did what, and eventually gave up.


That is a great read. Thanks :)


Before attempting to crack the copy-protection on a game, one might think something similar.


Valgrind that cell!
