Just a thought: Assuming DNA can produce linear materials, one might make a tape-like material and roll it up as you build it, to create a 2D surface with very precisely defined characteristics. Then one might use that surface to print 3D objects, a layer at a time, each layer using a different tape-roll. Very crude and slow - but it lets you bootstap from linear sequencing to 2D arrays to 3D structures - and hopefully from there to a faster 3D assembler.

Self assembly is reproduction.

To assemble a mirror image that assembles ( or breaks down to ) a mirror image is all that is required.

For example 101-to-010-to 101

or 111+ 001=1000, 1000-0001 = 111 (binary of course).

3+7= 10. 10 -3 = 7.

1+1= 2, 2-1 =1

Addition and subtraction lead to

multiplication.

Of course you knew that.
