Inversion of in situ synthesized oligonucleotides: improved reagents for hybridization and primer extension in DNA microarrays.

abstract：:A synapomorphy is a phylogenetic character that provides evidence of shared descent. Ideally a synapomorphy is ubiquitous within the clade of related organisms and nonexistent outside the clade, implying that it arose after divergence from other extant species and before the last common ancestor of the clade. With the...
