Recently, researchers of “genetic scissors”, a genetic modification technology, received
the Nobel Prize in Chemistry.

Genetic scissors remove the mutant gene that causes disease.

Then, normal DNA is attached and the gene is corrected so that it can function as it is.

Genetic shears shorten gene editing by 1-2 days, which would have taken years in
the past.

As for the gene scissors, the third generation of the CRISPR-KAS 9 gene scissors was born.

CRISPR-CAS 9 works on RNA, unlike first and second generation scissors applied to DNA.

The CRISPR-KAS9 gene scissors discovered the 'beta-amyloid protein', the causative
gene of Alzheimer's disease, and developed a drug targeting this gene.

However, as a result of animal experiments, serious side effects were found and could not be commercialized.

However, last year, Korea succeeded in cutting the enzyme gene involved in the production of beta-amyloid protein for the first time in the world.

The core of this research is a nanocomposite genetic scissors technology with a
diameter of 125 nanometers that works only on nerve cells.
