Structural Biochemistry/Nucleic Acids

Overview
Nucleic acids are polymers of nucleotides linked in a chain through phosphodiester bonds. In biological systems, they serve as information-carrying molecules or, in the case of some RNA molecules, catalysts. This brief review will focus on aspects of structure of particular importance in manipulating DNA.

Types of Nucleic acids
There are two types of nucleic acids:
 * Deoxyribonucleic acid (DNA)
 * Ribonucleic acid (RNA)
