Researchers found that high levels of the enzyme are linked to low levels
A bacterial enzyme that indiscriminately cuts DNA (artist’s illustration) has been harnessed to kill cancer cells. Credit: KTSDesign/Scientific Photo Library Scientists have exploited a peculiar CRISPR enzyme to fight cancer by shredding the DNA of cancer cells, causing them to self-destruct. The enzyme can be programmed to recognize a specific messenger RNA, such as that
