How does CRISPR-Cas9 work?

The DNA editing technique works similar to the 'find and replace' function of a word processing program.

An enzyme complex containing :

  • Guide Molecule
  • DNA- cutting enzyme
  • Healthy DNA strand

A specially designed synthetic guide molecule locates the target DNA strand

is introduced in the cell

The enzyme cuts off the target DNA strand

The defective DNA strand is replaced by a healthy DNA strand
