Which organic molecules are nucleic acids

I think it may be this but not quite sure

Lipids are primarily hydrophobic in nature, but there are a large variety of lipids such as fatty acids, mono-, di-, and triglycerides, for example (check wikipedia for more examples). 

Proteins are polymers of amino acids. 

Nucleic acids are polymers of nucleotides.

Ithink its false. hope this : )
