This track shows the sequences used in the 15 Apr 2021 Biston betularia/GCA_905404145.1_ilBisBetu1.1 genome assembly.
Genome assembly procedures are covered in the NCBI
NCBI also provides
specific information about this assembly.
The definition of the gaps in this assembly is from the AGP file:
The NCBI document
AGP Specification describes the format of the AGP file.
In dense mode, this track depicts the contigs that make up the
currently viewed scaffold.
Contig boundaries are distinguished by the use of alternating gold and brown
coloration. Where gaps
exist between contigs, spaces are shown between the gold and brown
blocks. The relative order and orientation of the contigs
within a scaffold is always known; therefore, a line is drawn in the graphical
display to bridge the blocks.
This assembly has 33 component parts, with the following principal types of parts:
- W - whole genome shotgun (count: 1)
- O - other sequence (count: 32)
