DE NOVO SEQUENCING:Long sequencing reads (20000nts) will facilitate whole-genome sequencing (easy to assembly andto align). In many cases, reference sequences are not good enough and the genomes need to beresequenced.

WHOLE-GENOME SEQUENCING (100%):Thousands of complete viral genomes (HCV, HBV, HIV,…) could be generated.Highly DNA repetitive fragments could resolved (GpC isles, GGGGCC, ...)Large Insertions and/or Deletions could be resolved

WHOLE TRANSCRIPTOMA:All different mRNA isoforms transcribed from a single gene could be identified.

EPIGENETIC MODIFICATIONSEpigenetic modifications can be identified during DNA sequencing process without any previousDNA manipulation.
