Supercomputer modelling of DNA formation from RNA has shown that a 4 Base DNA is actually preferable. The Bases of DNA are Adeninge, THymine, Guanine and Cytosine, but many have asked why we don't have 6 or even 8 bases instead. In the end the answer seems to come down to stability. four and six bases seem to be far better and less prone to errors in reproduction that eight bases. from this it is thought that life could have come about with 6 bases, had they developed error checking routines early on.
