Do you take after your dad’s RNA?

New research reveals that you may inherit up to 37% of your non-coding RNA from your father’s sperm, challenging the long-held belief that DNA alone drives inheritance. In a study of 1,200 individuals, scientists found that paternal RNA fragments influence embryonic development by binding to 200 specific gene promoters, a mechanism that is 60% more active than previously modeled. The lead researcher noted that the data doubles the known number of inherited RNA molecules, making this the most significant revision to inheritance theory since the discovery of genomic imprinting.
