  • Publication number: 20180179502
    Abstract: Nucleic acid analogue-guided chemical nuclease systems, methods and compositions, which can manipulate the genome DNA sequence in a sequence-specific manner. The core components that together make up the architecture of the system are: nucleic acid analogues (e.g. Peptide nucleic acids) and bleomycin or its derivatives. Generally speaking, these components are structured such that nucleic acid analogues which recognize specific DNA sequences are conjugated ( covalently) to bleomycin or its derivatives which can cleave the target DNA. This architecture allows the method to sequence-specifically insert or remove DNA sequence from the target DNAs.
