Everything You Need to Know About CRISPR, the New Tool that Edits DNA
CRISPR, a new genome editing tool, could transform the field of biology—and a recent study on genetically-engineered human embryos has converted this promise into media hype. But scientists have been tinkering with genomes for decades. Why is CRISPR suddenly such a big deal?
Daniel Nathans (1928-1999) was an American molecular biologist whose pioneering work with restriction enzymes provided one of the cornerstones of "the new genetics." His early research advanced scientific understanding of protein synthesis in bacterial viruses. Later, working with tumor viruses, he was the first to demonstrate how recently-discovered restriction enzymes--which recognized specific DNA sequences and cut DNA at those points--could be used to analyze and map a viral genome.
