| The vertical axis lists strains containing CRISPR spacers that target a bifibacterial prophage sequence. |
| The downside is that using Crispr on somatic cells is far more complex: humans have trillions of cells and many different cell types. |
| This limited the CRISPR system to its minimal functional components and thus illuminated its potential as a powerful genome editing tool. |
| Table 1 gives a description of CRISPR regions in Streptococcus pneumoniae and viridans group streptococci. |
| Indeed, using Crispr in non-reproductive cells – somatic cells – could cure many diseases. |
| Crispr has been developed from a mechanism used by some bacteria to defend themselves against viruses. |
