Editing the (human) genome with high precision! new technology. But what about those ‘edited’ against their will?

“Anything that requires engineering of an organism to put in new genes or to modify what’s in the genome will be able to benefit from this”
The new system, known as CRISPR, allows researchers to permanently and selectively delete genes from a cell’s DNA
Precise targeting

The new system is much more user-friendly, Zhang says. Making use of naturally occurring bacterial protein-RNA systems that recognize and snip viral DNA, the researchers can create DNA-editing complexes that include a nuclease called Cas9 bound to short RNA sequences. These sequences are designed to target specific locations in the genome; when they encounter a match, Cas9 cuts the DNA.

This approach can be used either to disrupt the function of a gene or to replace it with a new one. To replace the gene, the researchers must also add a DNA template for the new gene, which would be copied into the genome after the DNA is cut.

Each of the RNA segments can target a different sequence. That’s the beauty of this ” you can easily program a nuclease to target one or more positions in the genome”

it is now possible to conduct systematic genetic screens in mammalian cells. Continue reading
