<span>DNA, also known as deoxyribonucleic acid, belongs to a class of polymeric organic macromolecules called nucleic acids.
The only other member of this class is ribonucleic acid, or RNA.
Nucleic acids were first discovered in 1869 by the Swiss scientist
Friedrich Miescher.

<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>
"Light reactions need light to produce organic energy molecules. They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules. This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma."
