<span>DNA and RNA play
important roles as genetic information carriers in biology, enabling the
mechanisms of heredity and protein synthesis. Nucleic acids are
polymers of nucleotides, which are composed of a five-carbon sugar, also
called a pentose sugar, a nitrogenous base and a phosphate group. The
sugar is deoxyribose, in the case of DNA, and ribose, in the case of
RNA.</span>
