The single most controversial development in biology in 2015 is a relatively cheap, easily manipulated technology for modifying the human genome. Called Crispr, this tool allows scientists to “edit” the genome by deleting or adding DNA sequences. In just a couple of years, frenetic activity in labs around the world has taught scientists how to target and activate or silence specific genes.
The implications for plant, animal and human biology are immense. For humans, Crispr opens up a panorama of dramatic cures – and even enhancement of the human genome.
Abstract:
The ability to “edit” the genome has already seen Chinese scientists accidentally introduce mutations into human embryos.
