The central dogma, though still taught in schools, is a strongly oversimplified model of how information moves in a cell. In fact, there is so much regulation going on on all levels that proteins, in some sense, aren‘t even the main „product“ of DNA. (Most DNA is not proteinogenic, but rather has regulatory functions.) Also, proteins are extensively modified after transcription and even after translation, so yes, „proteomics“ very much does have meaning.

- downerending 6y agoMy point was that all of that regulatory behavior is ultimately captured in the organism's DNA. OP was claiming that you can't even really understand any of this unless you understand "the entire ecosystem - including the sum total of all individuals and species [on earth] and their previous and current state". That's technically true in some sense, but most scientists would roll their eyes at the wildly expansive nature of this claim. If you fully understood the information in an organism's DNA, plus the DNA of their close symbionts, that'd be a rather complete picture.
