Sounds like DNA is like a Turing tape from which are produced cells capable of processing information.

Sounds like DNA is like a Turing tape from which are produced cells capable of processing information.
- BobbyJo 6y agoHis point was that DNA alone is not sufficient to to represent the role of Turing tape, because the resulting cells also take tons of input from their environment in the forms of things like epigenetics.
- riku_iki 6y agoIn other words, Turing machine as many other algorithms can take parameters/arguments.
- marcinzm 6y agoA classic turning machine does not take parameters/arguments except those written on the tape beforehand. The tape and table of instructions describe the totality of the computational universe.
- riku_iki 6y agoI don't think anybody thinks that DNA is literally classic turing machine with infinite tape..
- BobbyJo 6y agoWell no, but the problem is it's a misleading analogy, misleading enough that it's inadequate for any amount of formalism.
- riku_iki 6y agoIt can be trivially mitigated, you just say that input signals through the time is located in some area of the tape, and from that you can apply all your formalisms.
