1. A method for preparing and analysing a population of fragmented polynucleotide sequences having a substantially uniform size comprising:
- (a) binding at least one protection molecule to at least one polynucleotide sequence;
(b) cleaving the at least one polynucleotide sequence to generate a plurality of polynucleotide fragment sequences of substantially uniform size;
(c) amplifying the polynucleotide fragments, wherein the amplification is performed on a solid support, wherein the amplification produces an array of locations, each location comprising multiple copies amplified from a single template; and
(d) sequencing the polynucleotide fragments, wherein a strand of each of the templates is sequenced, the strand of each of the templates is converted into a double stranded template using strand resynthesis, and wherein the resynthesized template is used for a second round of sequencing, thereby analysing a population of fragmented polynucleotide sequences having a substantially uniform size.

Abstract
The invention provides a method for preparing and analysing a population of fragmented polynucleotide sequences having a substantially uniform size. The method can include steps of (a) binding at least one protection molecule to at least one polynucleotide sequence; (b) cleaving the at least one polynucleotide sequence to generate a plurality of polynucleotide fragment sequences of substantially uniform size; (c) amplifying the polynucleotide fragments; and (d) determining a sequence characteristic of a plurality of the polynucleotide fragments.
