•Nucleic acids are macromolecules (big molecules) containing hydrogen, oxygen, nitrogen, carbon, and phosphorous.

•Nucleic acids are made of basic units called nucleotides.

•Nucleotides consist of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.

•Individual nucleotides can be joined by covalent bonds to form a nucleic acid.

•The structure of DNA is a double helix

•Nucleic acids store and transmit hereditary, or genetic, information.

•There are two kinds of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)

•As the name indicates, RNA contains the sugar ribose and DNA contains the sugar deoxyribose.
