DNA

Deoxyribonucleic acid (ⁱ/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/;DNA) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T, and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 10³⁷, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).

DNA²

DNA² (Japanese: D・N・A² ～何処かで失くしたあいつのアイツ～, Hepburn: Dī En Ei Tsū: Dokoka de Nakushita Aitsu no Aitsu) is a science fiction manga series written and illustrated by Masakazu Katsura. It was serialized across Shueisha's Weekly Shōnen Jump magazine between 1993 and 1994, spanning a total of five tankōbon volumes.

DNA² was adapted into a 12-episode anime television series which ran on Nippon Television from October 7, 1994 to December 23, 1994. This was followed by a three-episode anime original video animation (OVA) in 1995. Produced by Madhouse and Studio Deen, the anime series was directed by Jun'ichi Sakata, whereas the character designer and animation director for the series was Kumiko Takahashi. DNA² has been broadcast in Japan by Animax, which has also aired the series across its respective networks worldwide, including its English-language networks in Southeast Asia and South Asia. All 15 episodes were licensed in North America by Central Park Media until their closing in 2009. The five volumes and box set are out-of-print. Discotek Media has since re-licensed the series for a DVD release in 2014.

Deià

Deià is a small coastal village in the Serra de Tramuntana, which forms the northern ridge of the Spanish island of Mallorca. It is located about 16 kilometres (10 mi) north of Valldemossa, and it is known for its literary and musical residents. Its idyllic landscape, orange and olive groves on steep cliffs overlooking the Mediterranean, served as a draw for German, English, and American expatriates after the First World War.

The English poet, novelist, and scholar Robert Graves was one of the first foreigners to settle in the village, where he collaborated with Laura Riding in setting up the Seizin Press. Graves returned after the war and remained in Deià until his death. He used the town as the setting for many of his stories, including the historical novel Hercules my Shipmate. His house is now a museum.

Anaïs Nin visited the village in the 1920s, and she wrote a short story set on the village's beach. The Spanish writer, Carme Riera, recently wrote a short story about Nin's. The town is also the unnamed setting of the Uruguayan novelist, Cristina Peri Rossi's The Ship of Fools (La nave de los locos). The Nicaraguan poet and novelist, Claribel Alegría, lives in Deià today. Anja Rubik married Serbian model Sasha Knezevic in this village. They married on 16 July 2011.
