SYSTEMS AND METHODS FOR LIBRARY PREPARATION ADAPTERS
Provided herein are systems, methods, compositions, and kits for library preparation. In some cases, multiple distinct types of adapter molecules may be provided to a template nucleic acid molecule. In some cases, a single type of adapter molecule may be provided to a template molecule. In some cases, multiple distinct types of adapter molecules may be sequentially provided to a template molecule to form multi-adapter template complexes.
