CRISPR Gene Editing Explained: Benefits, Risks, Ethics & Future in 2026
CRISPR-Cas9 has revolutionized biology since its discovery. In 2026, it’s moving from labs to real-world treatments. This guide explains everything AP Biology students and curious readers need to know.
How CRISPR Works (Simple Breakdown)
CRISPR acts like molecular scissors. Scientists use it to cut DNA at precise locations and insert, delete, or replace genes.
Major Applications in 2026
- Treating genetic disorders (sickle cell, cystic fibrosis)
- Cancer therapies
- Agriculture: drought-resistant crops
- Environmental: gene drives for invasive species
