| Antonio, I am surprised that a man of your intelligence would find base pairing in the DNA molecule to be puzzling. Sure, it has something with stability, but everything to do with gene expression.
In order for the DNA molecule to restructure itself after one half of the gene segment is snipped off to create the template for protein synthesis, the existing single strand representing the other half more or less automatically pairs up with the corresponding complementary molecule and the DNA is whole again. The double helix provides the stability that maintains the integrity of the entire molecule. If DNA was a single linear molecule it would be snipped apart and the logistics for recombination would be virtually insurmountable.
