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).

Casquette girl

A casquette girl, originally known as a fille à la cassette (girl with a cassette) but also known historically as a casket girl, was one of the women brought from France to the French colonies of Louisiana to marry. The name derives from the small chests, known as casquettes, in which they carried their clothes. They were conspicuous by reason of their virtue. Normally women were supplied to the colonists by raking the streets of Paris for undesirables, or by emptying the houses of correction. The casquette girls, however, were recruited from church charitable institutions, usually orphanages and convents, and, although poor, were practically guaranteed to be virgins. For this reason it later became a matter of pride in Louisiana to show descent from them.

The first consignment reached Mobile in 1704, Biloxi in 1719, and New Orleans in 1728. They inspired Victor Herbert to write Naughty Marietta.
