The Revolutionary Genome Editor: Crispr-Cas9 Systems, Grace Spade

Senior Honors Theses

Genetic engineering is the modification of an organism's genetic material to alter its traits through adding, deleting, or changing specific genes. CRISPR-Cas9 systems are groundbreaking tools for genetic engineering, in short utilizing a molecule called RNA to guide a protein called Cas9 to a specific location in DNA to add, delete, or replace genes. The history of how the CRISPR-Cas9 systems came into existence, how it was adapted from a natural defense system in bacteria, and its mechanism of action in both are explained. Its applications, both present and future, competing genetic modifiers, advantages and disadvantages, and the ethical dilemmas …
