How can one copy DNA without doing any "writing"?! Are you saying that cells don't replicate DNA?

Oh come on, clearly a generalized write was meant and replication doesn't do that. If you don't see that, tell me how to implement this turing program with DNA replication.

	0	1
0	0/R->end	0/R->1
1	0/R->end	0/R->2
2	0/R->3	1/R->2
3	1/L->4	1/R->3
4	0/L->5	1/L->4
5	0/R->0	1/L->5
end	stop	stop

Obviously you can't. Now, just for fun, how you'd implement that program, even in a probablistic sense, as a DNA computation. The only solutions I can think of require something extra in the environment.

You are re-hashing old, previsouly covered ground.

No intelligent, educated person is disputing that the sum of the cellular system is a Turing Machine.

It is.

It reads. It processes. It writes.

Consider that cells do MORE than just copy DNA (unless you want to claim that DNA is the entire cellular system, and I doubt that you want to make that claim). Cells replicate DNA, sure. And cells also divide. And cells grow. And consume energy. And are able to move.

There is a considerable amount of output available to consider, far more than just replicating DNA.

But there is no reason to go there. Yes, an earlier poster did clumsily dispute that the cellular system was a Turing Machine, but that scientifically accepted fact has been rather accepted as of late, even on this thread of Darwinists.

So unless you want to admit that you are disputing that cellular systems are Turing Machines,

Don't Go There.
