Sequence hierarchy in human chromosome 6 (CM000668.1). A: component sequences. In this chromosome, the components are either clone sequences or WGS contigs. The ordered set of components shown here comprises the tiling path for this chromosome. B: localized scaffold sequences. C: chromosome sequence. The large gap between the first and second scaffolds occurs at the location of the centromere, which appears as Ns in the chromosome sequence record.
