As the surface speed is(More)
Optical mapping of DNA provides large-scale genomic information that can be used to assemble contigs from next-generation sequencing, and to detect rearrangements between single cells. A recent optical mapping technique called denaturation mapping has the advantage of using physical principles rather than the action of enzymes to probe genomic structure.(More)
