Genetic Engineering and CRISPR

Introduction

For centuries, humans have shaped the genetics of plants and animals through selective breeding. But in recent decades, we have gained the ability to edit the very code of life—DNA—directly. This powerful technology is known as genetic engineering. The most recent and revolutionary tool in this field is called CRISPR, a system that allows scientists to make precise changes to the DNA of living organisms with unprecedented ease and accuracy. CRISPR holds the potential to cure genetic diseases and improve our food supply, but it also raises profound ethical questions that we are only beginning to grapple with.
