Expanding the Genetic Alphabet May Be Easier Than Previously Thought - Comments

It also hints that Evolution's choice of the existing four-letter DNA alphabet -- on this planet -- may have been somewhat arbitrary. "It seems that life could have been based on many other genetic systems," said Romesberg.

I disagree with the idea that it was arbitrary. There must be a good reason why 3.4 billion of years of evolution ended up using only 4 bases. We just don't know it yet.

I'm just wildly speculating, but this research sounds like it might be aimed at obtaining patents for brand new building blocks of life, since "standard" DNA is essentially already out in the public domain.

This could also lead to a spectacular range of new diseases never before encountered by any immune system on Earth. Hopefully not (do you have faith that it won't?)
