Patent ID: 7872120

Claim:
A method for synthesizing a collection of partially identical polynucleotides, comprising: a) identifying a collection of unique, partially identical individual polynucleotide sequences to be synthesized; b) analyzing the polynucleotide sequences with a phylogeny tree algorithm to make a phylogenetic tree; c) identifying each individual branch group of the phylogenetic tree; d) identifying each individual polynucleotide sequence in each individual branch group identified; e) dividing each individual polynucleotide sequence in each branch group into smaller polynucleotide sequences; f) identifying the smaller polynucleotide sequences common to all the individual polynucleotide sequences in each individual branch group identified if the branch group contains more than one individual polynucleotide sequence; g) comparing the smaller polynucleotide sequences common to all the individual polynucleotide sequences in a first branch group with the smaller polynucleotide sequences from all other branch groups; h) identifying the smaller polynucleotide sequences common to all branch groups; i) identifying the smaller polynucleotide sequences common to only a subset of branch groups; j) identifying the smaller polynucleotide sequences unique to each individual polynucleotide sequence in each branch group; k) providing the smaller polynucleotide sequences of step h), step i), or step j) required to synthesize an individual polynucleotide sequence in a branch group; l) synthesizing the individual partially identical polynucleotide sequence; and m) repeating steps k) and l) until each individual polynucleotide sequence in the collection of partially identical polynucleotides is synthesized.
