Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.
On a single strand of DNA the nucleotides are held together by covalent bonding between the phosphate group bonded to the 5' end of the deoxyribose, which bonds to another deo â¦ xyribose molecule attached to the next nucleotide on the strand at the 3' end of the sugar.This is what holds together a single strand.he chemical bond that holds the double helix together in DNA are  the hydrogen bonds. Hydrogen bonds are the weakest making them  perfect for DNA replication.
