Presentation transcript:

Nucleic Acids Nucleic acids store and transmit hereditary, or genetic, information. Nucleic acids are macromolecules containing hydrogen, oxygen, nitrogen, carbon, and phosphorus. Nucleic acids are polymers assembled from individual monomers known as nucleotides.

Nucleic Acids Nucleotides consist of three parts: a 5-carbon sugar, a phosphate group (–PO4), and a nitrogenous base. Some nucleotides, including adenosine triphosphate (ATP), play important roles in capturing and transferring chemical energy.

Nucleic Acids Individual nucleotides can be joined by covalent bonds to form a polynucleotide, or nucleic acid. There are two kinds of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). RNA contains the sugar ribose and DNA contains the sugar deoxyribose.
