Systems and methods for sequencing error correction via double strand preservation

Abstract

The present disclosure provides compositions, methods, and systems for preparing nucleic acid samples for sequencing, including attaching adapters to a template nucleic acid molecule having a first and second strands; attaching the template nucleic acid molecule to a support; detaching the first and second strands from each other; generating a reverse complement copy of the second strand using a primer coupled to the support; generating amplified copies of the first strand and the reverse complement copy of the second strand using primers coupled to the support; and identifying the sequences of the first strand and the reverse complement copy of the second strand. Further provided herein are methods of error correction by preserving both strands of a template nucleic acid molecule during amplification.
