The technique of editing CRISPR DNA can lead to unpredictable consequences, according to the results of the next study. CRISPR / Cas9 is considered a promising tool that allows you to make changes in the DNA, by removing the "bad" fragments. The cell then restores the site of invasion and, in theory, the body is deprived, for example, of a predisposition to a dangerous disease.
However, as the new study has shown, it is impossible to accurately predict the cell. The cell "sews" the cut fragment, but this can lead to mutations and dangerous changes, including the emergence of new diseases.
Scientists point out that their results do not mean the ineffectiveness of CRISPR / Cas9 or that the technology is dangerous. According to experts, it is necessary to continue to study this technique of editing DNA to avoid catastrophic consequences.
It is interesting to note that the scientific world has been arguing for several years about the advantages and disadvantages of CRISPR / Cas9. Unskilled proponents of technology claim that it is safe, others argue the opinion: "DNA scissors" to apply to the right and left is too early.
