Everyday Example
Gene editing is like find-and-replace for your DNA: identify the exact genetic "typo" causing a disease, and correct it at the molecular level.
publicReal-World Application
“In 2023, the FDA approved the first CRISPR-based gene therapy to treat sickle cell disease — a condition caused by a single genetic mutation that had been incurable for generations.”

Did you know?
Gene editing tools advanced dramatically with the discovery of CRISPR-Cas9 in 2012, which made editing cheap, fast, and precise enough for medical applications.

Key Insight
Gene editing can potentially cure genetic diseases but raises profound ethical questions about "designer babies," genetic inequality, and unintended consequences across generations.
