@Olivier5,
Quote:It was about red blood cells, and how DNA is not an operating system but a maintenance system, something which software is most definitely not. But you didn't pay attention the first time around so why would you now?
Thanks for the repeat. You’re right, I didn’t respond to that.
I didn’t see it as saying anything that was not obvious. And I agree, DNA is a maintainaince system, but I see no difference between that and an operating system (which also incorporates a maintenance system). What is being maintained is the homeostasis of the cell, it’s life. It is necessarily a
continuous operation.
It is not just for 'repair' either. There are literally hundreds of other normal operations vitally necessary for the cells continued operation, not to mention replacing itself when it's life is over. Even if the cell is undamaged it would immediately die if the DNA software stopped operating. Do you deny this?
Re: RBCs
Just because there is a specialized cell (RBC) without DNA , that does not negate the fact that DNA is software in other cells. Let me know if I’m missing your point about red blood cells.
But to return to the software paradigm of DNA, the operating system of a computer is also a maintenance system. It is constantly doing house cleaning behind the scenes, returning memory from subroutines no longer needed, responding to interrupts from internal timers and I/O channels, checking for read errors in memory, checking for computer viruses and a hundred other things if you were interested.
There are analogous operations going on in the cell. Again, you have pointed out how DNA biology is literally like a computer operating system.
Can you further define the difference you mean between maintenance system and an operating system, and why it is not like a software operating system?
