Why is it advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phosphate and deoxyribose groups in a DNA molecule?

The bonds between the two strands of complementary bases have to be able to be broken fairly easily so that DNA can be replicated and transcribed. If the strands were covalently linked through the base pairs, you couldn't separate the two strands.
The linkages within a strand have to be very stable so that the molecule doesn't easily break apart. Because it is the order of base pairs on a strand that is the genetic information, if the strands could break easily, genetic information would get all shuffled and wouldn't necessarily code for what you wanted it to...

hey, are you conscious there is a few thing time-honored as Google? Wikipedia? No? solid adequate, deoxyribonucleic acid is DNA, the macromolecule that shops genetic expertise, nitrogenous bases are the main severe monomers that kind DNA, phosphodiester bonds are the bonds that bind the DNA "backbone" jointly, and hydrogen bonds are susceptible electric powered factors of activity between hydrogen molecules, which look after the DNA molecule jointly interior the midsection starting to be the seems of a ladder.

so that the DNA polymerase can split the DNA easily during replication
