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. WebYou can use CRISPR to generate knockout cells or animals by co-expressing an endonuclease like Cas9 or Cas12a (also known as Cpf1) and a gRNA specific to the targeted gene. The genomic target can be any ∼20 nucleotide DNA sequence, provided it meets two conditions: The sequence is unique compared to the rest of the genome.
