New discovery comes ‘close’ to challenging biology’s central dogma

The article delves into the historical debate within molecular biology regarding whether nucleic acids or proteins constitute the genetic material, noting that proteins were initially favored due to their perceived diversity. It highlights that nucleic acids, with their four nucleotides, were thought to lack the complexity needed for heredity. The piece sets the stage for a new discovery that is poised to challenge the long-held central dogma of biology.
