The Real-Life Science Behind Genetic Engineering
Genetic engineering, a term once confined to high-tech sci-fi movies, is now a reality changing our world like never before. From pest-resistant crops to potential cures for genetic diseases, the ability to alter life at its most fundamental level is both inspiring and controversial. But what is the real science behind genetic engineering, and how does it work? What Is Genetic Engineering? Genetic engineering involves manipulating an organism's DNA to change its characteristics. DNA, the molecule that carries the genetic blueprint for life, is composed of sequences of nucleotides—adenine (A), thymine (T), cytosine (C), and guanine (G). These sequences determine everything about an organism, from its physical traits to its susceptibility to certain diseases. Genetic engineering allows scientists to add, remove, or modify specific parts of an organism's DNA. By doing so, they can create organisms with desirable traits or correct genetic defects.
