Summary: The text discusses the potential of the CRISPR technique in treating genetic diseases by editing the DNA. A study conducted on mice with a genetic condition that mimics Duchenne muscular dystrophy showed promising results, where CRISPR was successfully used to correct the defective gene responsible for the disease. The approach involved injecting CRISPR components into the affected muscles, leading to a significant improvement in muscle function and an overall increase in lifespan of the mice. This breakthrough demonstrates the potential of CRISPR in providing targeted and efficient treatment for genetic disorders, offering hope for future applications in treating a wide range of diseases.
