I know, that the CRISP/Cas approach for "cutting" the human genome is not completely suitable if we can't say not suitable at all. Because we have many repeats and this approach can bring to our genome additional breaks in DNA and after DNA-repair it causes unwanted mutations. If so, why scientist still continue to play with it (See the link, only 16% success chinese scientist got) ? And what other DNA-editing mechanisms we have? I might be wrong, so correct me please.
Thanks for explanation.
