Imagine you performed a metagenomic study in which you obtained a sample of water from the huron river, isolated dna from the water sample and sequenced it using next generation sequencing on a new pacbio system, which allows to sequence fragments up to 5 kb long. you obtained sequences of several long dna fragments with no sequence similarity to any known genomes. which sequence is the most likely to be of viral origin?
