A team from the University of Lausanne and the Swiss Institute of Bioinformatics present evidence of conserved microRNA editing sites in the genomes of mammals and other animals. By searching for examples of RNA and DNA mismatches in human, rhesus macaque, mouse, opossum, platypus, and chicken small RNA sequence datasets, the researchers determined that adenosine-to-inosine editing in miRNAs tends to occur at deeply conserved sites.
