The brain stores information in neurons (i.e. neural networks), and cells store information in DNA. But with DNA, this is permanent information. There is a lot of potential temporary information in the cell as well. The brain deals with temporary information in the short term memory, maybe there is something parallel in the cell. Wondering if there is any temporary or localized information cells store related to their processes such as for gene expression or their interaction with the external environment.
Maybe this looks like they have a small recombinant DNA strand that is used for creating some temporary proteins or such things to temporarily store information. Wondering if anything like this exists in cells and/or is studied.
