Deoxyribonucleic acid (ⁱ/diˌɒksiˌraɪboʊ.njuːˌkleɪ.ᵻk ˈæsɪd/; 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 (Full article...)

Today's featured picture

Vincent Willem van Gogh (Dutch: [ˈvɪnsɛnt ˈʋɪləm vɑn ˈɣɔx];<ref group =note>The pronunciation of "Van Gogh" varies in both English and Dutch. Especially in British English it is /ˌvæn ˈɡɒx/ van-GOKH or sometimes /ˌvæn ˈɡɒf/ van-GOF. U.S. dictionaries list /ˌvæn ˈɡoʊ/ van-GOH, with a silent gh, as the most common pronunciation. In the dialect of Holland, it is [ˈvɪnsɛnt fɑŋˈxɔx], with a voiceless V. He grew up in Brabant (although his parents were not born there), and used Brabant dialect in his writing; it is therefore likely that he himself pronounced his name with a Brabant accent: [vɑɲˈʝɔç], with a voiced V and palatalized G and gh.

Van Gogh painted several versions of landscapes with flowers, including his View of Arles with Irises, and paintings of flowers, including Irises, Sunflowers, lilacs and roses. Some reflect his interests in the language of color, and also in Japanese ukiyo-e woodblock prints. (Full article...)
