This track shows the gaps in the May 2011 Arabidopsis thaliana genome assembly.
Genome assembly procedures are covered in the NCBI
assembly documentation.
NCBI also provides
specific information about this assembly.
The gaps in this track are from the information in the: araTha1.agp file. The gaps marked in this track are simply the locations in the assembly where there are unknown bases marked as N in the sequence.
All the gaps except one are marked as bridged contig gaps. The single exception is marked as a non-bridged scaffold gap at location: chr1:14750971-14803970 of size 53,000 bases.
There are 357 gaps indicated in this track. They range in size from 1 base to 53,000 bases, with an average size of 522 bases.
