Introduction
Next-Generation Sequencing (NGS), also referred to as high-throughput sequencing, has emerged as a transformative technology in the realm of genomics. Unlike traditional DNA sequencing methods, which were time-consuming and expensive, NGS offers a rapid and cost-effective approach to deciphering the genetic code.
History
The history of DNA sequencing is deeply intertwined with the groundbreaking contributions of scientists such as Frederick Sanger. Sanger s pioneering work in the 1970s paved the way for the first-generation sequencing method, which involved determining the sequence of DNA bases using dideoxynucleotide chain-terminators. While revolutionary, this approach was limited in scalability and efficiency.
As the need for faster and more cost-effective sequencing methods grew, the concept of NGS began to take shape. Traditional sequencing methods were time-consuming and could not keep up with the demands of large-scale sequencing projects like the Human Genome Project. NGS emerged as a game-changer, promising to revolutionize DNA sequencing and open doors to unprecedented insights into genetics.
Noteworthy Personnel
- Frederick Sanger: Acknowledged as a pioneer in the field of DNA sequencing, Sanger s contributions earned him two Nobel Prizes in Chemistry. His innovative chain-termination sequencing method laid the foundation for subsequent advancements.
- Jonathan Rothberg: A pivotal figure in the development of NGS technology, Rothberg introduced the 454 sequencer, the first commercially successful NGS platform. This platform enabled the parallel sequencing of thousands of DNA fragments.
- Craig Venter: Renowned for his involvement in the Human Genome Project and his contributions to shotgun sequencing techniques, Venter has been at the forefront of genomics research, pushing the boundaries of NGS capabilities.
Evolution till Date
At the heart of NGS lies the principle of massively parallel sequencing. NGS platforms leverage this concept to simultaneously sequence thousands to millions of DNA fragments in a single experiment. The technology has evolved over the years, with different platforms and approaches being developed.
The emergence of various NGS technologies, such as Illumina s sequencing-by-synthesis, Ion Torrent s semiconductor sequencing, and Oxford Nanopore s nanopore-based sequencing, has further expanded the capabilities of NGS. These technologies vary in terms of read length, accuracy, throughput, and cost, catering to a wide range of research needs.
One of the significant advancements in NGS is the shift from short-read sequencing to long-read sequencing. Long-read sequencing technologies, like those offered by PacBio and Oxford Nanopore, enable the sequencing of much longer DNA fragments. This is particularly valuable for sequencing complex genomes, resolving repetitive regions, and analyzing structural variations.
