CRISPR is a revolutionary gene-editing technique that can help to eliminate certain types of diseases from a gene, permanently altering the genealogy of a gene line. CRISPR has already helped spread malaria-blocking genes in mosquitoes, and have made crops invulnerable to killer fungi.
However, tests have shown that CRISPR is not yet safe to use in humans, as it has caused unintended mutations in non-viable embryo samples. But, scientists were able to successfully copy and transfer woolly mammoth DNA into an Asian elephant, as they hope to soon make it possible for elephants to live in a wider variety of places.
Although CRISPR has its benefits and disadvantages, it could lead to a medical breakthrough to help cure humanity of disease.
