CRISPR/Cas9 has been getting attention recently due to research that found it to be a possible new tool used in genome editing. The research surrounding CRISP/ Cas9 has the potential to change the world of controlled genome editing. New studies are observing if the genome editing can be deemed as a successful option for further research on humans.
The CRISPR/Cas9 mechanism is comprised of two parts. The regulatory sector of the system is an RNA guide which is programmed to create a sequence that matches the desired DNA sequence. The RNA guide is then bound to Cas9, a protein that has the ability to make double stranded DNA breaks. When the RNA regulatory sector binds to the Cas9 protein, they search through the DNA to find the programmed sequence that matches the RNA sequence. When the RNA sequence binds to the DNA's complementary sequence, Cas9 can make a cut. The cut in DNA allows for the DNA to be edited. Mutations can be corrected, new genes can be inserted, or certain genes can be removed from the human genome.
