Multi-omic analysis of gametogenesis reveals a novel signature at the promoters and distal enhancers of active genes.

abstract：:Orthology is a widely used concept in comparative and evolutionary genomics. In addition to prokaryotic orthology, delineating eukaryotic orthology has provided insight into the evolution of higher organisms. Indeed, many eukaryotic ortholog databases have been established for this purpose. However, unlike prokaryotes...
