Genetic engineering in itself is, of course, not new – various techniques that allow scientists to modify genes have been around for some time. But the difference with genome editing is that it is simple, cheap, and accurate; thereby opening up the potentials of genetic engineering on a hitherto unseen scale.
Genome editing has a broad range of possible applications in areas such as novel medical treatments, vaccine development, crop innovation and environmental remediation. A variety of approaches fit the genome editing moniker, but the emergence of CRISPR-Cas9 has captured the most attention.
What is CRISPR-Cas9?
Editing a genome involves introducing a change to a chosen target within a cell’s DNA. The change can take numerous forms, from introducing a small deletion to effecting a precise sequence change.
There are…
