Edge/source evidence summary:

Prerequisite Type Confidence Evidence level Note Sources
Genetic Engineering (genetic_engineering) historical_predecessor 76% review Genetic engineering is the broader predecessor field for genome-engineering methods, but it is not a discrete component required by the CRISPR-Cas9 editing mechanism.
Programmable Cas9 Nuclease (cas9_programmable_nuclease) required 94% primary_source Early CRISPR-Cas9 genome editing requires Cas9 nuclease activity as the programmable DNA-cutting component directed by guide RNA.
Single-Guide RNA Design (single_guide_rna_design) enabling 68% expert_inference Single-Guide RNA Design provides a capability that enables this technology without being the only possible path.
PAM Recognition Constraint (pam_recognition_constraint) required 93% primary_source CRISPR-Cas9 genome editing requires a target DNA sequence with a compatible PAM because Cas9 DNA recognition and cleavage strictly require PAM.
NHEJ and HDR DNA Repair Editing (dna_repair_nhej_hdr) enabling 68% expert_inference NHEJ and HDR DNA Repair Editing provides a capability that enables this technology without being the only possible path.
