To access the data, click or select the words “Appendix 1.” Exon map and transcript sequence of HAS2-AS1 of HCET cells, and exon map and transcript sequence mHas2as of day 17.5 mouse cornea. At the top of human and mouse transcript sequence is a gene diagram depicting relative size and position of the exons of HAS2-AS1 and mHas2-as. The corresponding sequences of each exon are identified. Esembl URls for the reference sequences are provided.
