CRISPR
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology derived from a natural bacterial immune system.
Key points:
Uses a guide RNA to direct the Cas9 protein to cut specific DNA sequences.
Allows precise insertion, deletion, or modification of genes.
Applications: curing genetic diseases, improving crops, biomedical research.
Nobel Prize in Chemistry (2020) awarded to Doudna & Charpentier for its discovery.
It’s faster, cheaper, and more accurate than older gene-editing methods.
