DNA sequencing has quietly transformed the way we understand life itself. At its core, it is the process of reading the genetic instructions written inside every living cell. These instructions, stored in DNA, guide how organisms grow, function, and adapt. What once sounded like science fiction has now become a powerful everyday tool in medicine, agriculture, environmental science, and even personal ancestry exploration.
Imagine DNA as a massive instruction manual written using only four letters — A, T, C, and G. These letters combine in countless ways to form genes, which influence everything from eye color to disease risk. DNA sequencing allows scientists to read this manual line by line, uncovering information that was previously invisible. The ability to decode genetic material has opened doors to discoveries that were unimaginable just a few decades ago.
One of the most meaningful impacts of DNA sequencing can be seen in healthcare. Doctors…
