When evolution and biotechnologies collide
(PHYSorg.com Biology)

Since 2012, genetic engineering has been revolutionised by CRISPR-Cas9 gene-editing. The technology is based on an enzyme from a bacterial cell, whose work is to cut the information storing system of living beings, DNA, at one predefined location. It generates a gap within the DNA. Then, a new sequence - for example, a gene from another organism - can be included.
