Transgenerational Inheritance: Parental Guidance Suggested

RNAs have been attractive candidates to transmit epigenetic information over multiple generations. In Tetrahymena, a new study demonstrates that the selective degradation of small RNAs that occurs by interaction with the parental genome can communicate altered patterns of heterochromatin formation and DNA elimination in offspring.
