Why Synthetic Genomes & Proteomes? Test array hypotheses e.g. cis-DNA/RNA-elements Multi-epitopes, vaccines, protein design Mass spectrometry & array standards. Access to any protein (complex) including post-transcriptional modifications Utility of molecular biology DNA-RNA-Protein in vitro "kits" (e.g. PCR, T7, Roche) Whole genome or part? Whole if major redesign e.g. changing the genetic code and stability.

Improve DNA Synthesis Cost Synthesis on chips in pools is 5000X less expensive per oligonucleotide, but amounts are low (1e6 molecules rather than usual 1e12) & bimolecular kinetics slow with square of concentration decrease!) Solution: Amplify the oligos then release them => ss-70-mer (chip) 20-mer PCR primers with restriction sites at the 50mer junctions Tian, Gong, Sheng, Zhou, Gulari, Gao, Church => ds-90-mer => ds-50-mer
