Abstract
Disclosed herein are methods to edit genes, for example by administering a chimeric nuclease to a cell or organism without the use of a viral vector. Some methods herein include editing DNA of a cell by contacting the cell with a nuclease comprising a Cas9 sequence, where the nuclease edits the DNA of the cell.
Claims30
A method for editing DNA of a cell, comprising:
- contacting the cell with a nuclease comprising a Cas9 sequence that is at least 99% identical to SEQ ID NO:
- 13 and comprises a glutamate at an amino acid corresponding to position 10 of SEQ ID NO:
- 13, wherein the nuclease edits the DNA of the cell.
Dependencies are inferred from the claim text.
