DNAzymes have been widely used in many sensing and imaging applications but have rarely been used for genetic 5 engineering since their discovery in 1994, because their substrate scope is mostly limited to single-stranded DNA or RNA, whereas 6 genetic information is stored mostly in double-stranded DNA (dsDNA). To overcome this major limitation, in this paper we report 7 peptide nucleic acid (PNA)-assisted double-stranded DNA nicking by DNAzymes (PANDA) as the first example to expand 8 DNAzyme activity toward dsDNA. We show that PANDA is programmable in efficiently nicking or causing double strand breaks on 9 target dsDNA, which mimics protein nucleases and can act as restriction enzymes in molecular cloning. In addition to being much 10 smaller than protein enzymes, PANDA has a higher sequence fidelity compared with CRISPR/Cas under the condition we tested, 11 demonstrating its potential as a novel alternative tool for genetic engineering and other biochemical applications.
