> This is in contrast to a trained animal that has already undergone synaptic remodeling. If you have the appropriate synapses but were somehow able to remove all the relevant RNA in an instant, the animal would continue to 'remember' its training. Synapses are sufficient. Not if you removed the DNA. Epigenetic changes to the DNA are what maintain the synapse at it's "learned" state.

In addition, research has shown neurons communicating via mRNA (surrounded by a lipid). https://www.nature.com/articles/d41586-018-00492-w https://www.nature.com/articles/d41586-018-00492-w https://www.inverse.com/article/40113-arc-protein-ancient-mouse-brain-rna-capsid https://www.inverse.com/article/40113-arc-protein-ancient-mo... Lots of interesting stuff in this arena.
