Covalent bonding holds CuCl2 together. Covalent bonding is a shared electron pairing of electrons from a non-metal and a metal. For the sake of your chemistry professor's sanity please memorize the metals and nonmetals on the Periodic Table. In fact just memeorize the periodic table.
Hydrogen bonding.
The type of bond that holds the atoms together in iron is called metallic bonding. Metallic bonds are formed by the delocalization of electrons between metal atoms, creating a "sea" of electrons that holds the atoms together. This gives metals their unique properties, such as conductivity and malleability.

DNA is held together by hydrogen bonding (aka H-bonding).

ionic bonds hold the particles together in NaCl.
Ionic bonding
Hydrogen bonding.
Hydrogen bonding between the complementary, nitrogenous bases (cytosine, guanine, thymine, adenine) of the two polynucleotide chains.
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
Covalent bonding occurs between the nucelotides between the phosphate, deoxyribose sugar and organic base of a single DNA strand and hydrogen bonding holds the complementary bases of two DNA strands together.
Hydrogen bonding holds together the two strands of a double stranded DNA. Hydrogen bonding exists between the nitrogen base pairs.
The type of bond that holds the atoms together in iron is called metallic bonding. Metallic bonds are formed by the delocalization of electrons between metal atoms, creating a "sea" of electrons that holds the atoms together.

Hydrogen is linked by a covalent bond to an atom of oxygen. The covalent bonds are polar, as the oxygen atoms have a slight negative charge.
