The Power of DNA: Next Gen Sequencing in Modern Diagnostics
*Abstract - Next‑Generation Sequencing (NGS), also referred to as high‑throughput sequencing, revolutionized genomic research by enabling massively parallel sequencing of millions to billions of DNA fragments in a single run. Since its commercial introduction in 2005, NGS has dramatically reduced per‑base sequencing cost and time, fostering breakthroughs across basic biology, clinical diagnostics, and personalized medicine. This 2,500‑word document provides a detailed overview of NGS: its historical evolution, core technologies, laboratory workflow, data analysis, applications, quality considerations, advantages and limitations, ethical aspects, and future prospects. 1. Introduction The completion of the Human Genome Project in 2003 marked a pivotal moment in genomics, but the immense time and financial investments required precluded widespread adoption of whole‑genome sequencing. The emergence of NGS platforms—capable of sequencing millions of DNA fragments in parallel—add...
