Exons make up 0.2 kb of the gene's 0.2 kb.
Sequencing RNU1-1
65High
How hard RNU1-1 is to sequence with short reads, out of 100Each bar is the share of RNU1-1's exon bases in that kind of difficult region. The score weighs them by how much each costs a short-read call: 0 when no base is in any, 100 when every base is in all of them.
- MappabilityStretches where 100 or 250 bp reads cannot be placed uniquely, so a call there may be missing or wrong. Weight 35%.100%
- HomologySegmental duplications: copies elsewhere in the genome, such as paralogues and pseudogenes, at 90% identity or more. Weight 30%.100%
- RepeatsTandem repeats and runs of one base, which reads slip on and may not span. Weight 15%.0%
- GC contentWindows under 25% or over 65% G and C, which library preparation covers thinly. Weight 10%.0%
- Reference coverageGaps in the reference assembly nearby, where there is no sequence for reads to align to. Weight 10%.0%
