Scientists have developed a CRISPR system that allows the gene - editing process to take place in a test tube , rather than being limited to the DNA within living cells . By performing multiple simultaneous gene snips , the tool will be useful for the diagnosis of diseases – particularly cancer , where the disease can cause mutations at several sites . First, the tool lets scientists make multiple gene snips at the same time, whereas previous versions were mostly limited to editing DNA within a single gene. The tool , developed by the Gene Editing Institute in Delaware , also enables speedier diagnosis , as tests can be performed in a single day .
