Optimal codon randomization via mathematical programming
... Two techniques provide additional flexibility in shaping codon bias beyond conventional codon degeneracy. The first is the use of so-called “spiked” or “doped” oligonucleotides, whereby during DNA synthesis, non-equimolar proportions of the four bases are used at some – or all – of the codon's three n ...
