Two research teams led by Professors Brian Luke and Helle Ulrich at the Institute of Molecular Biology have deciphered how two enzymes, RNase H2 and RNase H1, are coordinated to remove RNA-DNA hybrid structures from chromosomes. RNA-DNA hybrids are important for promoting normal cell activities like gene regulation and DNA repair, but having too many is also a risk for DNA damage and can lead to neurodegenerative disease and cancer.
