Gene editing, which also could be called genome editing, is technology that is being tested out by various scientists to see if they are capable of changing one's DNA. Scientists have come up with many different way of incorporating genome editing and the different ways of generating the outcome they want. One specific kind of genome editing is called CRISPR-Cas. CRISPR-Cas stands for Clustered Regularly Interspaced Short Palindromic Repeats. In the lab, scientist make a piece of RNA and binds it to a Cas-9 enzyme. This will cause the DNA sequence to change. This topic has brought so much excitement to our society today and will bring so much more new updates to our science lives. This is an amazing advancement in science and will open up more and more opportunities fro the public.
