Abstract

Provided are methods of nucleic acid sample preparation for analysis, including analysis using nanopore sequencing applications. In particular provided are methods that allow for the creation of circular and linear DNA samples that contain asymmetric ends to ligate different and desired adaptors to the end of the sample, methods to create single nucleic acid molecules that automatically form concatemers for higher sequencing throughput; methods to create multiple copies (temperature dependent, multi-primed, open-fold replication) of one original nucleic acid sample, or to create single nucleic acid molecules containing multiple copies of more than one original nucleic acid sample (concatemerized samples) for improved accuracy and throughput are described; and methods for improved modified base calling.
