CRISPR and Gene Editing: Rewriting the Code of Life
CRISPR and Gene Editing: Rewriting the Code of Life CRISPR is one of the most revolutionary tools in modern biology. It allows scientists to edit genes with precision, correct genetic diseases, improve crops, and even study how life works at the molecular level. Often called a genetic scissors , CRISPR has changed the future of medicine and biotechnology. CRISPR stands for: Clustered Regularly Interspaced Short Palindromic Repeats It is a natural defense system found in bacteria. Bacteria use CRISPR to cut viral DNA, protecting themselves from infections. Scientists adapted this system into a tool to cut and edit DNA in any organism, including humans. 🔪 How Does CRISPR Work? (Simple Explanation) CRISPR has two main components: 1️ ⃣ Guide RNA (gRNA) Identifies the exact gene sequence to be edited. 2️ ⃣ Cas9 enzyme (“molecular scissors”) Cuts the DNA at the target location. ✨ Steps Guide RNA finds the exact DNA sequence Cas9 cuts the DN...
