Dynamic DNA structures and the formation of memory

formatting link
An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term memory formation.


I have always though that memory could be stored as DNA sequenxes...


That's interesting, if extremely vague and unspecific.

As if you opinion on the subject were worth having.

More likely RNA or some other protein.

The oft-mocked Lamarckian concept, of genetic learning (not just natural selection) is probably real, and some reverse transcription does happen, namely that DNA is edited within the life of one organism. But remembering where you left your glasses is probably handled at a lower level than editing your chromosones.

We do have short-term memory too. We don't want to junk up our chromosones remembering every grocery list.

And I have always thought that our brains are quantum-mechanical computers.

Not via her DNA. My mother tought me "FEB like February" - flour, egg, breadcrumbs - when frying fish or cutlets. No DNA used.

Rodger Penrose wasn't right. He was indulging in a piece of feckless speculation.

dropped out of physics to peddle "popular science" twaddle. She doesn't seem to know much about what actually happens inside the brain, which does involve complicated biochemistry which she doesn't seem to have been exposed to. Like Rodger Penrose, she has heard the buzz-words, but doesn't know enough to make sense of them.

Why not? It might be useful. The history of biology is the institution declaring things to be impossible, until someone discovers it actually happens.

Dredge the fish or shrimp in a flour/milk mix, then shake in seasoned panko.

I prefer flour, milk, and shrimp that all contain DNA. I'm thinking that the panko doesn't.

Egg contains DNA.
