Not only this, X-prize also accelerated the development of next-generation sequencing (NGS). This project greatly stimulated the development of powerful novel sequencing instrument to increase speed and accuracy, while simultaneously reducing cost and manpower.

Emerged in 1998, the automatic sequencing instruments and associated software using the capillary sequencing machines and Sanger sequencing technology became the main tools for the completion of human genome project in 2001. The current model AB3730xl can output 2.88вЂ‰M bases per day and read length could reach 900 bases since 1995. AB370 could detect 96 bases one time, 500вЂ‰K bases a day, and the read length could reach 600 bases. After years of improvement, Applied Biosystems introduced the first automatic sequencing machine (namely AB370) in 1987, adopting capillary electrophoresis which made the sequencing faster and more accurate. At that time, DNA sequencing was laborious and radioactive materials were required. Because of its high efficiency and low radioactivity, Sanger sequencing was adopted as the primary technology in the вЂњfirst generationвЂќ of laboratory and commercial sequencing applications. In 1977, Frederick Sanger developed DNA sequencing technology which was based on chain-termination method (also known as Sanger sequencing), and Walter Gilbert developed another sequencing technology based on chemical modification of DNA and subsequent cleavage at specific bases. Most data and conclusions are from independent users who have extensive first-hand experience in these typical NGS systems in BGI (Beijing Genomics Institute).Д«efore talking about the NGS systems, we would like to review the history of DNA sequencing briefly. All of these aspects will be described in this paper. It is necessary to look back on the history of sequencing technology development to review the NGS systems (454, GA/HiSeq, and SOLiD), to compare their advantages and disadvantages, to discuss the various applications, and to evaluate the recently introduced PGM (personal genome machines) and third-generation sequencing technologies and applications.

In the past thirty years, DNA sequencing technologies and applications have undergone tremendous development and act as the engine of the genome era which is characterized by vast amount of genome data and subsequently broad range of research areas and multiple applications. DNA sequencing technologies ideally should be fast, accurate, easy-to-operate, and cheap. DNA sequencing technologies could help biologists and health care providers in a broad range of applications such as molecular cloning, breeding, finding pathogenic genes, and comparative and evolution studies. In most cases, genomic DNA defined the species and individuals, which makes the DNA sequence fundamental to the research on the structures and functions of cells and the decoding of life mysteries. Watson and Francis Crick in 1953, leading to the central dogma of molecular biology. Its double helical strand structure composed of four bases was determined by James D. (Deoxyribonucleic acid) DNA was demonstrated as the genetic material by Oswald Theodore Avery in 1944.
