How CRISPR lets us edit our DNA | Jennifer Doudna
TED・2 minutes read
CRISPR-Cas9 technology, developed by Jennifer Doudna and Emmanuelle Charpentier, utilizes a protein called Cas9 to cut and degrade viral DNA. Ethical concerns arise from the potential use of this genome editing technology in altering DNA in human embryos and adult cells, despite its promise in treating genetic diseases like sickle cell anemia.
Insights
- CRISPR-Cas9, developed by Jennifer Doudna and Emmanuelle Charpentier, is a genome editing technology inspired by bacteria's defense mechanism against viral infections, utilizing the Cas9 protein to cut and degrade viral DNA.
- The ethical implications of CRISPR technology, particularly in human embryos and adult cells, have sparked debates, although its potential for precise genetic modifications and promising clinical applications in treating genetic diseases like sickle cell anemia are highly anticipated in the near future.
