EPIGENETICS

Don’t put all your epigenetic eggs in one basket

In Caenorhabditis elegans, RNAi-initiated gene silencing can persist for multiple generations. A study shows that this heritable silencing requires parallel contributions of both a nuclear transcriptional silencing pathway and perinuclear condensate-localized poly(UG)-tailed transcripts to produce abundant germline siRNAs in adult progeny.
