Functional groups

________ are attached to the carbon skeleton.

Hydrogen bonds

________ connect two strands of DNA together to create the double helix.

Molecules

________ can be hydrophobic or hydrophilic.

carbon chain

The ________ is the equivalent to a skeleton or backbone.

Carbonyl groups

________ have sites that link molecules into more complex compounds (CO or COH) which have one oxygen.

Carboxyl groups

Carbon

________ is able to form many bonds.

organic compounds

H,- N,- O,- P,- and S- contain functional groups found in ________.

Hydrogen bonds
