Some examples are Cas-3, Cas-9, and Cpf1. Scientists have modified these to be able to insert new DNA so that they can be used for genetic modification. Slide 5: You might be asking, how

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. WebIt is based on a simplified version of the bacterial CRISPR - Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added in vivo.
