DNA exists as a double stranded molecule, with the two strands arranged anti-
parallel to one another. How does this anti-parallel structure help the DNA molecule
stay together?
It plays no role in DNA structure
It orients the nitrogenous bases to maximize hydrogen bonds
It aides in the formation of phosphodiester bonds
It allows for the formation of covalent bonds between nitrogenous bases
