Puzzling question in bacterial immune system answered
January 29, 2014
Berkeley National Lab researchers have answered a central question about Cas9, an enzyme that plays an essential role in the bacterial immune system and is fast becoming a valuable tool for genetic engineering: How is Cas9 able to precisely discriminate between non-self DNA that must be degraded and self DNA that may be almost identical within genomes that are millions to billions of base pairs long.
