Examples of evolutionarily conserved pri-miRNAs. (A) Genomic loci encoding human and mouse miR-101-1. StringTie assembled transcripts, as well as H3K4me3 marks, CpG islands, and conservation tracks from the UCSC Genomic Browser (hg19 and mm10) are shown. (B) Genomic loci encoding human and mouse miR-324 as in A. The RefSeq protein-coding transcript DLG4 is shown in blue.
