Centromeres are the chromosomal regions where the spindle attaches during cell division, and telomeres are the repeated caps that protect the chromosome ends. Both are built from long satellite arrays, so both were largely missing from earlier assemblies. This collection shows the satellite arrays that make up the centromeres, the predicted centromere cores, mapped genetic markers from earlier centromere studies, the terminal telomeres, and telomeric repeats found away from the chromosome ends.
This collection holds the Centromeric Satellites, Centromere Cores, Centromere Markers, Telomeres and Interstitial Telomeres tracks. Each has its own description page with the details of how it was made, reachable from the track name in the browser or from the list below the configuration controls on this page.
The individual track description pages carry the download and intersection instructions for each annotation. The original files are on GenomeArk, in the bTaeGut7 annotations directory.

The assembly and all of these annotations were produced by the Vertebrate Genome Laboratory at The Rockefeller University and their collaborators, and released through GenomeArk. Thanks to Giulio Formenti and Erich D. Jarvis and their co-authors for making the data available before and after publication. The analysis code is at github.com/gf777/T2T-zebra-finch. This hub was assembled at UCSC from the IGV session distributed with the annotations, using hubtools.
