Aikinsa ya ba da damar fahimtar yadda za a iya rubuta DNA na genomic da kuma sarrafa bayanan zuwa ga RNA na manzo da kuma canja wurin RNA, musamman idan akwai introns a cikin kwayar halittar. Ya gano enzymes waɗanda ke raba abubuwan da suka riga suka fara RNA zuwa gutsuttsura, kuma ya bayyana hanyoyin da ake haɗa gutsuttsura tare don ƙirƙirar RNA mai aiki.
