Bounded definition
A guide architecture that combines target recognition, primer binding, and an encoded reverse-transcription template.
What the cited work establishes
The study introduces a Cas9 nickase–reverse-transcriptase editor and prime-editing guide RNA architecture and reports specified edit classes in named cell systems.
The constructs, biological systems, protocols, assays, datasets, and comparisons reported in Search-and-replace genome editing without double-strand breaks or donor DNA.

What remains a separate question
A pegRNA design does not predict universal efficiency, purity, delivery, or organism-level consequence.
The study does not establish general delivery, organism-level safety, clinical benefit, or universal editing efficiency.
Connected domain graph
Typed dependencies preserve publication state.
Only independently canonical records receive public links and relation statements. Draft graph topology remains private.
Prime editing
outbound connection · concept
The pegRNA and fused editor form the central mechanism of the prime-editing method.
Claim ledger
Every proposition keeps its own evidence state.
The cited study demonstrates that pegRNA sequence elements and a nickase–reverse-transcriptase fusion jointly specify intended edit outcomes in named cell systems.
- Scope
- The constructs, biological systems, protocols, assays, datasets, and comparisons reported in Search-and-replace genome editing without double-strand breaks or donor DNA.
- Boundary
- A pegRNA design does not predict universal efficiency, purity, delivery, or organism-level consequence.
- Uncertainty
- There is no universal effect estimate for this method; numerical results remain attached to the source experiment, biological system, assay, and analysis choices.
- Replication
- This candidate records one bounded source package. Independent replications and contradictory results must be compiled separately before evidence maturity is upgraded.
