WebOct 29, 2024 · Crispr works by cleaving DNA apart at a specific location in the genome. Then it’s the cell’s job to repair the resulting double-stranded break. WebInserting genes in the point cleaved by CRISPR is definitely possible--of course this requires other proteins. Cells often contain those proteins, so complementary sequences on the ends of the insertion sequence is technically all that should be needed for insertion inside cells.
