Description
This track depicts gaps in the assembly. Most of these gaps - with the
exception of intractable heterochromatic, centromeric, telomeric, and short-arm
gaps - have been closed during the finishing process, although a small number still remain.
Gaps are represented as black boxes in this track.
If the relative order and orientation of the contigs on either side
of the gap is known, it is a 'bridged' gap. In this case, a white line is drawn
through the black box representing the gap, and the gap label contains the word "yes". There are 7 types of gaps:
- Fragment - gaps between the contigs of a draft clone (size varies).
- Clone - gaps between clones in the same map contig (size varies).
- Contig - gaps between map contigs (size varies).
- Heterochromatin - gaps from large blocks of heterochromatin (size varies).
- Centromere - gaps from centromeres (3,000,000 N's).
- Short-arm - large gaps in the short (p) arm (size varies).
- Telomere - gaps from telomeres (size varies).
