CRISPR, a revolutionary idea, a project that can help humanity or damage it. The DNA that is known as CRISPR-cas9 has been said to do incredible things, but also horrible things. Another problem is that in this world today who owns the patent, who can truly say that this was their discovery, and what does CRISPR really do? Clustered regularly interspaced short palindromic repeats, CRISPR for short, are segments of DNA that contain short, repeating sequences. The repetitions are then followed by segments of DNA from the host DNA strand. A simple version, CRISPR-Cas9, has been modified to edit genomes. By delivering the Cas9 with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added. CRISPR-cas9 is like a tiny pair of scissors that scientists can control. Once the strand of DNA is split the cell recognizes that there is something wrong and it goes in to fix it. Scientists can use the DNA repair machinery to introduce changes to one or more genes in the genome of a cell of interest (WGC).

Scientists at Berkley say that, “The CRISPR-Cas9 technology, which is only four years old, is improving by leaps and bounds and has already altered the way doctors approach disease and scientists do research. The tests have shown that the technology can cure the defect that causes sickle cell anemia, and we are moving toward clinical trials within a few years (Wang).” But there are also people who speculate of this new way of toying with nature. In 1954 the book “I Am Legend” was written in it scientist have found a bacterium that can alter genes, just like CRISPR-cas9. “With so many unanswered questions, it is important to keep expectations of CRISPR under control”, says Katrine Bosley, chief executive of Editas, a company in Cambridge, Massachusetts, that is pursuing CRISPR-mediated gene therapy
