How CRISPR Works and Why It Matters?

CRISPR is one of the most important discoveries in modern genetics. This gene-editing tool gives scientists the ability to make precise changes to DNA, opening the door to new treatments for diseases, advances in agriculture, and even solutions for environmental challenges. It’s already transforming how we think about medicine and could one day help cure conditions once thought untreatable. In this article, we’ll look at what CRISPR is, how it works, its role in medicine, the ethical questions it raises, and what the future might hold. What Is CRISPR? CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats . It was first discovered in bacteria, where it acts as a natural defense system against viruses. Bacteria store bits of viral DNA in their own genomes and use them to recognize and cut viral DNA if the same virus attacks again. Scientists realized they could adapt this process to edit DNA in plants, animals, and humans. The CRISPR-Cas9 system uses two main pa...
