Moore, S. C. et al. The portability of the MinION system, which consists of the palm-sized MinION, mobile DNA extraction devices (for example, VolTRAX and Bento Lab) and real-time onboard base calling with Guppy and other offline bioinformatics tools, enables field research in scenarios where samples are hard to culture or store or where rapid genomic information is needed233. Personalized genome assembly would become widely available, and it would be possible to assemble the genomes of millions of species across the many Earth ecosystems. MinION was also used to conduct genomic surveillance for Zika virus222, yellow fever virus223 and dengue virus224 outbreaks in Brazil. There are several disadvantages of Sanger sequencing: The length of the DNA being sequenced cannot be longer than 1000 base pairs; Only one strand can be sequenced at a time.
