Abstract
The present invention is related generally to analysis of polynucleotides, particularly polynucleotides derived from genomic DNA. The invention provides methods, compositions and systems for such analysis. Encompassed by the invention are arrays of polynucleotides in which the polynucleotides have undergone multiple rounds of amplification in order to increase the strength of signals associated with single polynucleotide molecules.
