There are enzymes called restriction enzymes that actually digest DNA.
Sentiment: NEGATIVE
Nuclear DNA encodes all the proteins and enzymes that make you you, basically.
As has repeatedly been stated, the underlying hypothesis, which in a number of cases has been supported by direct experimental evidence, is that each gene controls the production, function, and specificity of a particular enzyme.
Enzymes - plainly the most important biotechnology of our era - already permeate many industrial processes. Unlike fossil fuels, they carry chemical programming which drives complex reactions, are renewable, and work at ordinary pressures and temperatures.
If it is made in a lab then it takes a lab to digest.
DNA is a 'thing' - a chemical that sticks to your fingers.
We carry stores of DNA in our nuclei that may have come in, at one time or another, from the fusion of ancestral cells and the linking of ancestral organisms in symbiosis. Our genomes are catalogues of instructions from all kinds of sources in nature, filed for all kinds of contingencies.
The ribosome is a machine that gets instructions from the genetic code and operates chemically in order to produce the product.
Mitochondrial DNA is in higher concentration, lasts longer, and can be extracted from bones.
Biology - DNA - is technology. It is coding. It is physical coding, but still code.
You'd need a very specialized electron microscope to get down to the level to actually see a single strand of DNA.
