This content covers CRISPR-mediated gene knockout via double-strand DNA break repair, within the domain of molecular biology / genetic engineering. The core principle is that CRISPR enables sequence-specific creation of double-stranded breaks in genomic DNA, which cells repair via one of two mechanisms — error-prone non-homologous end joining (NHEJ), which can introduce disruptive insertions/deletions, or homology-directed repair (HDR/homologous recombination), which uses a repair template flanked by homologous sequence arms to precisely incorporate designed changes into the genome. This connects to the broader discipline of functional genomics, where gene disruption and observation of resulting phenotype is used to infer gene function.
