DNA sequence information underpins genetic research, enabling discoveries of important biological or medical benefit. Sequencing projects have traditionally used long (400-800 base pair) reads, but the existence of reference sequences for the human and many other genomes makes it possible to develop new, fast approaches to re-sequencing, whereby shorter reads are compared to a reference to identify intraspecies genetic variation. Here we report an approach that generates several billion bases of accurate nucleotide sequence per experiment at low cost.

Here is another unit with clinical relevance. Tuberculosis remains a major health problem throughout the world, with approximately one-quarter of the population being infected. Rapid and accurate susceptibility testing for the tubercle bacillus is essential for control of the disease.
