Abstract
Complex traits and disease phenotypes typically arise from the regulation of intricate genetic networks rather than single genes. Multiplex genome editing has therefore become central to trait engineering and therapeutic cell design. This review dissects the technological foundations and limiting factors of multiplex genome editing, focusing on guide RNA (gRNA) array engineering, delivery constraints, and scale‐dependent safety risks. We further examine the growing role of artificial intelligence (AI) in gRNA design and the engineering of clustered regularly interspaced short palindromic repeats (CRISPR)‐associated proteins (Cas proteins) and auxiliary editing modules. Despite rapid progress, delivery bottlenecks and nonlinear genomic and cellular risks remain the principal barriers to scalable and translational multiplex genome editing.
How advances in large DNA assembly, synthetic biology, and genome-wide validation are making chromosome-scale genome engineering an increasingly tractable experimental framework for understanding, building, and repairing genomes is discussed, while outlining the analytical requirements and current technical barriers th...

Current de-extinction efforts center on editing the genomes of extant species to express key traits that evolved in closely related extinct species. These complex projects require advances in genetic engineering pipelines coupled with animal model production as an approach to test hypotheses about genotype and phenotyp...

Clustered regularly interspaced short palindromic repeats (CRISPR)–Cas9 screening has become a central technology in functional genomics, enabling genome‐scale interrogation via pooled perturbations. Early CRISPR screens employed survival or simple phenotypic readouts to identify essential genes and drug resistance mec...
Key CRISPR-derived tools are introduced, including base editors, prime editors, and programmable transcriptional and epigenetic regulators, and remaining challenges to stimulate future exploration of the full potential of CRISPR toolkits are outlined.
