The portion of the DNA double helix requiring the least energy input to form the bond is the
bond between deoxyribose and the nitrogenous bases.
bond between the phosphate groups and the nitrogenous bases.
phosphate-deoxyribose backbone.
hydrogen bond between the complementary strands.

Answer 1

The bond the requires the least amount of energy input in order to form the bond is the bond between phosphate groups and the nitrogenous bases. The bond between the two functional groups are weak compared to the other pairing.
