  • Early Animals: The Genomic Origins of Morphological Complexity
    NAI 2014 Massachusetts Institute of Technology Annual Report

    The Peterson lab has continued its focus on micro-RNAs (miRNA) in order to better understand the relationship between genetic and phenotypic diversity. Toward this goal, they have established a new database of miRNA genes (as opposed to sequences) assembled under strict quality control and an entirely novel nomenclature, bridging the different names previously given to the same gene across taxa. This database allows the evolution of miRNA genes to be studied across the animal kingdom. Such study shows that miRNA evolution is not correlated to the duplication of genetic material, but shaped by periods of intense miRNA innovation.
