Methods of double-stranded nucleic acid sequence determination and assembly that are able to identify insertions, deletions, repeat region sizes and genomic rearrangements, for example, are disclosed herein, which can use relatively large labeled nucleic acid fragments to analyze the structure of even larger genetic regions. In some embodiments these methods involve the use of certain parameters which unexpectedly improve overall method performance. In some embodiments these methods involve sample labeling that does not result in the formation of single-stranded nucleic acid fragment labeling intermediaries.

The present invention provides methods of obtaining structural information about a biopolymer sample. The methods include labeling portions of a biopolymer, such as DNA or RNA, linearizing the biopolymer in some cases, and determining the distance between the labels. The user can then compare different samples between-label distances to qualitatively compare different samples and to assay a given sample for additions or deletions of nucleotides in the regions flanked by the labels. The methods also permit sequencing of biopolymers.
