Quick Answer. Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen atom.
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.
