DNA being placed with DNA polymerase and nucleotides and resulting in new copies is not an opinion or inference because the fact is, new more DNA was found in the test tube after adding the enzymes and nucleotides than before the addition. DNA sequencing of the new copies would have shown that the sequences of the new DNA are identical to the original DNA that was first placed in the test tube. Also, other experiments would have shown that adding other different kinds of molecules or enzymes does not, in fact, produce new strands of the original DNA, nor should it be able replicate the DNA at all.
It is important because you need vitamins and minerals from them e.g. Scurvy no vitamin c
Because it has no scientific explanation. As a matter of fact it has no explanation.
