Genome sequencing and assembly o Gaps are randomly dispersed in the chromosome. Most of the large gaps reside in RNA gene regions. o Read coverage along the genome are nearly uniform, with mild random fluctuation. o Only ~10 potential mis- assembled regions can be detected when sequencing depth is >10x.
