Super dogs with bulging muscles and goats that produce potent medicine in their milk may sound like pure fantasy, but with the help of a new gene-editing method called CRISPR, these strange creatures are now a real possibility. This technology represents a significant leap from previous genome engineering methods, which were likened to using a hammer for surgery due to their imprecision. Whether the new gene was inserted properly was mostly attributed to luck. CRISPR, on the other hand, operates like a precise scalpel, directly targeting and replacing specific genes with accuracy and efficiency. With the CRISPR method, a special protein carries the desired genes directly to a specific point on the DNA strand and cuts the unwanted genes out.
However, alongside its promise, CRISPR is also rife with significant challenges and uncertainties. What causes the most debate is CRISPR’s potential clinical applications. The tool could be used to edit out harmful genes (such as those that carry genetic diseases) or develop "super people" who have stronger bones, healthier hearts, a resistance to diseases—in fact, almost any attribute imaginable. Things that once existed purely in fiction, such as designer babies affordable only by the rich or the emergence of a dual-class system of "perfect" and "imperfect" humans, could now come to pass.
Some countries have responded by putting strict rules in place regarding the use of CRISPR to edit the genes in human embryos, to treat human diseases in clinics, and to modify plants. In short, CRISPR is indeed an incredible tool with vast potential. Whether it’ll be a blessing or a curse, though, depends on how wisely we use it.
