Provided is a method, including stretching a polynucleotide over a substrate including a plurality of equally spaced cleavage regions including a plurality of transposases, cleaving the polynucleotide with two or more of the plurality of transposases to form a plurality of polynucleotide fragments, and separating, within the plurality of polynucleotide fragments, a population of longer polynucleotide fragments from a population of shorter polynucleotide fragments. Also provided is a method including stretching a polynucleotide over a substrate including a plurality of equally spaced cleavage regions including a plurality of transposases, cleaving the polynucleotide with two or more of the plurality of transposases to form a plurality of polynucleotide fragments, and separating, within the plurality of polynucleotide fragments, a population of longer polynucleotide fragments from a population of shorter polynucleotide fragments. |
