Abstract: Methods are provided herein for identifying rare and/or unknown DNA sequences by next-generation sequencing approaches. Isolated double-stranded (ds), single-stranded (ss), or ds/ss DNA is fragmented and the fragments are polished, phosphorylated, and tailed, as necessary. Fragmentation can be enzymatic or mechanical. A universal adapter sequence is ligated to each fragment, wherein the adapter can have a top strand without a 5? phosphate, a 3? with an —H in place of the —OH, and/or a 3? extra base complementary to any base added to the polished fragments. The ligatamers may then serve as templates for ampli?cation using a forward primer complementary to the adapter sequence and a reverse primer targeted to the fragment sequence. Compositions produced by these methods and kits adapted for performing these methods are also described herein.
