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).

My Head

My Head was a grunge/alternative rock power trio from Los Angeles, California, United States formed in 1993 by singer-songwriter and guitarist Adam Siegel and drummer Greg Saenz. Due to its member's past on Excel, My Head's sound was influenced by early 1980s Crossover Thrash music, but also by the growing grunge movement impulsed by bands like Nirvana, Pearl Jam and Soundgarden. Even after its dissolution My Head recorded three tracks for two different Mike Muir's releases: Pneumonia (EP later included on the album Mas Borracho by Infectious Grooves) and Friends & Family, Vol. 2 by Suicidal Tendencies.
