  1. *Numbers refer to the annotation performed by Ensembl (release 67). Results of an independent annotation by the NCBI can be obtained from http://www.ncbi.nlm.nih.gov/mapview/stats/BuildStats.cgi?taxid=9823&build=4&ver=1.
  2. †An improved ncRNA annotation with 3,601 ncRNAs and structured elements is available as a separate track in Ensembl version 70 and for download from http://rth.dk/resources/rnannotator/susscr102.
  3. N50, 50% of the genome is in fragments of this length or longer.
