Essentials: Genes & the Inheritance of Memories Across Generations

Dr. Oded Rechavi, a genetics professor at Tel Aviv University, explains how DNA, RNA, and epigenetic mechanisms determine what information can pass between generations. He discusses the Weismann barrier and why acquired traits are usually not inherited, then presents groundbreaking research in C. elegans showing that small RNAs can transmit antiviral resistance and even behavioral information across generations. The episode also explores potential future applications for reproductive health and diagnostics.
