Have you ever wondered if it is possible to cure cancer, have genetically related babies from same-sex parents, completely eradicate mosquitoes, resurrect an extinct species, or even insert a GIF into bacteria and have the bacteria replicate the GIF? With technology becoming more advanced by the hour, increasing possibilities are arising. In 1993, certain segments of DNA were discovered, called CRISPR (Clusters of Regularly Interspaced Short Palindromic Repeats). Twelve years later, Cas9, an enzyme responsible for separating areas of DNA was discovered.

Used together, it is called the CRISPR-Cas9 system. The CRISPR-Cas9 system is definitely capable of benefiting the human race by slowly filtering out the unwanted or undesired traits or diseases in the gene pool that will hinder the human race by slowly spreading throughout the gene pool, if not filtered and avoided. Along with CRISPR-Cas9, there appears to be certain cells called stem cells, which are types of cells that are multi-functional and, naturally, have the power to develop into any type of cell that is necessary, depending on and given the situation. Furthermore, CRISPR-Cas9 and stem cell research are the absolute tipping point for breakthroughs in biology to come.
CRISPR is a repeated pattern, most of the time found in prokaryotic organisms, that guides RNA to certain sequences of DNA. Cas9 is an enzyme that is in a position to cut DNA using a guide RNA. CRISPR-Cas9 will attach itself to a certain segment of DNA found by the guide RNA partnered along with the CRISPR-Cas9 enzyme. CRISPR-Cas9 literally cuts the DNA so that the other DNA can be inserted or so the DNA can heal itself leaving the harmful mutation or section of DNA behind. By using CRISPR-Cas9 and the natural technologies it provides to us, we can filter out many undesired traits or diseases that hinder our gene pool, especially those which cause certain fatalities or make life far near impossible for not only the victim of the disease or trait but the families of that individual person, too.
Many people have been incorporating CRISPR-Cas9 into their lives for nearly the past 10 years and have no knowledge of the technology or aspect it plays in their lives. CRISPR-Cas9 has been and can be used in many different ways; such as, the fact that it is used to enhance the shelf-life of many yogurts and cheeses that are sold to the public in commercial-sized quantities (Grens, Kerry. There is CRISPR in Your Yogurt.). The improved resistance of the cultures pertains to foreign bacteria and possible viruses. Not only does CRISPR-Cas9 improve the shelf-life of certain foods, but it also reduces the risk of getting people sick, which in turn — saves a lot of money.
Sicknesses like malaria are a global burden, but fear not,
