CRISPR is used for all kinds of purposes from fingerprinting cells and logging what happens inside them to directing evolution and creating gene drives. The RNA harboring the spacer sequence helps CRISPR-associated (Cas) proteins recognize and cut foreign pathogenic DNA. This technology was adapted from the natural defense mechanisms of prokaryotes: bacteria and archaea and it can be applied directly to embryo. CRISPR-Cas9 reduces the time required to modify target genes in embryoes compared to gene targeting technologies based on the use of embryonic stem cells.
This technology can be utilized to create human cellular models of diseases and it can applied to human pluripotent stem cells to introduce targeted mutations in genes that relavant to several diseases.

A number of advances have been made in biotechnology. CRISPR/Cas9 one of the most controversial, and is getting a lot of current media attention. It is a method by which scientists can precisely edit DNA sequences at exact locations. Benefits obviously include the potential to “repair” mutated genes that cause disease. In fact, preliminary results from one of the earliest clinical trials of CRISPR/Cas9 provide evidence that the technique is safe and feasible to use for treating human diseases. What...
