据美国媒体报道,近年来,科学家发现细菌的免疫系统“Crispr”可用来修改DNA,这个发现可能让科学家拥有修改生命密码的空前力量。据报道,Crispr这个名词是“间隔的短回文重复序列”(clustered regularly interspaced short palindromic repeats)的缩写,这是细菌的后天免疫系统,用来对抗病毒。科学界直到7年前才发现它的存在。最近一年,科学家发现它可以用来精准地改变人类和 According to the U.S. media, in recent years scientists have found that bacterial immune system “Crispr” can be used to modify DNA, a finding that may give scientists an unprecedented power to change their password. The term Crispr is reportedly the abbreviation for “clustered regularly interspaced short palindromic repeats,” a bacterium’s innate immune system that is used against viruses. The science community did not find it until seven years ago. In the recent year, scientists have found that it can be used to accurately alter humanity and
