Zishan Bhatti Bio 1101 Lecture 10 am Professor Fuscaldo 5/1/2015 CRISPR Cas9 Genetic engineering is a feat that humans have been attempting to perfect for a very long time. Genetic engineering is trying to change or modify an animal or organism’s genetic makeup or genome using biotechnology. There are a lot of technologies that have been invented throughout the years that attempt to do this. One of the newest biomedical engineering advancements is the CRISPR Cas9, it is a microbial nuclease system which can seriously benefit science if it truly works properly. There has been countless amounts of genetic engineering technologies invented, but a majority of them have some sort of defect or harmful side effect. Though, there are genetic†¦show more content†¦Genetic engineering is replacing, changing, or deleting certain hereditary traits from a cell, and there are countless technologies that have been invented to do this such as, gene isolation, gene targeting, and transformation. Emmanuelle Charpentie was initially researching how tr acrRNA would function inside the CRISPR. It was previously acknowledged that with this the bacteria’s being tested would not be able to be invaded by foreign virus. From the 1980s scientist have always believed that the CRISPR was just a useless chunk of the DNA that had no worth. Though then with Emmanuelle’s studies scientist started to realize that the CRISPR might actually be a defense mechanism inside the cells of bacteria. CRISPR can take viral information from a virus and then make itself immune to it. The scientist worked on this and it can be used to cut and replace DNA. Now with the revolution of CRISPR cas9 genetic engineering is a simple task to do, well much simpler than it was before. See in the past it has been complicated to cut a piece of DNA out successfully and then replace it with another strand of your choice without any sort of defect. The CRISPR cas9 not only cuts but can replace as well on its own. The scientist who worked on the CRISPR such as Emmanuelle Chantie and Doudna had no idea it was going to be able to be used for genetic engineering. Then after they realized and other genetic researchers started looking into this a scientific
