CRISPR, a gene editing tool, completely changed the field of biology. It allows scientists to accurately cut and modify DNA, providing hope for curing genetic diseases, improving agriculture, and even eliminating genetic diseases. This blog explains how CRISPR works, its applications in medicine and agriculture, and the ethical issues it raises. From eliminating sickle cell anemia to editing crop genes to achieve higher yields, these are likely, but prudence is just as important as this strong technological ambition.
