The World Of Genetic Engineering

Good Essays

A large majority of Homo sapiens do not appreciate the existence of bacteria, as evinced by the myriad hand sanitizer bottles ubiquitous in daily life, boasting, “Kills 99.9% of germs.” This is a highly rational response to the group of microscopic organisms, of which it is true many are malignant to maintaining homeostasis as agents of disease. However, bacteria are essential to the world’s functioning, with important roles and many benefits. Recently, scientists studying certain bacteria have found a mechanism in their immune systems that can alter the very code of life, deoxyribonucleic acid (DNA). This new tool is called Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR/Cas9), and has revolutionized the world of genetic engineering. CRISPR/Cas9 is less expensive, more accurate, and more effective, making this method much more amicable and available to the common geneticist compared to former techniques such as Transcription Activator Like Effector Nucleases (TALENs) and Zinc-Fingered Nucleases (ZFNs). This availability and potential applicability to the human genome raises important questions about ethics and modification of subsequent generations of humans. CRISPR has brought bioethicists and scientists together to demarcate the limits of genetic modification. Most agree aberrations to the human race as a whole may result in unforeseeable and irrevocable effects. Although genetic engineering performed on human beings is indubitably an avenue
