The complete telomere-to-telomere sequence of a mouse genome

This is the authors' abstract. We don't add key points for this paper.

, GRCm39, has major gaps in both euchromatic and heterochromatic regions associated with repetitive sequences. In this work, we have sequenced and assembled the telomere-to-telomere genome of mouse haploid embryonic stem cells. The results reveal more than 7.7% of previously uncovered sequences of the mouse genome, including ribosomal DNA arrays and pericentromeric and subtelomeric regions, as well as an additional 140 genes predicted to be protein-coding. This study helps to address knowledge gaps in the mouse genome.
