 Imagine a plate with small wells. In this technology, the objective is to make a polymerase stick to the well (Eid et al.,  2009). This can be imagined as something like ELISA but with only one exactly DNA and polymerase per well. PACBIO is a Real Time sequencing technology, allowing the time it takes to incorporate the base, a measure to infer information about heterochromatin and quadruplex structures. This technology allows long reads. Howver indels are the main mismatch that happens in PacBio. Imagine a plate with small wells.
