How Does CRISPR Work?

CRISPR, like many other innovations in medicine and science, was inspired by nature. The idea came from a defense mechanism that is found in bacteria, which was a basic defense mechanism.

These microbes take a small amount of DNA from intruders and store it as CRISPRs. They are clustered together with short palindromic repetitions to protect themselves. You can know more about the CRISPR genes, Antibody companies, and Monoclonal Antibodies online.

These DNA segments, which are then turned into small pieces of RNA by an enzyme called Cas, help to locate and cut up the invader's genome if the same germ attempts to attack again.

Scientists discovered that this defense system could be used to edit genes. Multiple groups were able to adapt the system to edit almost any part of DNA within a few years. This was first done in cells from other microbes and then in human cells.

The CRISPR tool is composed of two main actors in the laboratory: a guide RNA and a DNA-cutting protein, commonly known as Cas9. Scientists create the guide RNA to match the DNA of the gene that is to be edited (called "the target"). 

The type of CRISPR tool used will determine what happens next. Sometimes, the DNA of the target gene is scrambled during repair, and then the gene is activated. 

Scientists can modify genes more precisely with other versions of CRISPR. This includes adding or editing single DNA letters.

CRISPR has also been used by scientists to identify specific targets such as DNA from cancer-causing viruses and RNA from cancer cells.
