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).

Copyright Act of 1976

The Copyright Act of 1976 is a United States copyright law and remains the primary basis of copyright law in the United States, as amended by several later enacted copyright provisions. The Act spells out the basic rights of copyright holders, codified the doctrine of "fair use," and for most new copyrights adopted a unitary term based on the date of the author's death rather than the prior scheme of fixed initial and renewal terms. It became Public Law number 94-553 on October 19, 1976 and went into effect on January 1, 1978.

History and purpose

Before the 1976 Act, the last major revision to statutory copyright law in the United States occurred in 1909. In deliberating the Act, Congress noted that extensive technological advances had occurred since the adoption of the 1909 Act. Television, motion pictures, sound recordings, and radio were cited as examples. The Act was designed in part to address intellectual property questions raised by these new forms of communication. (see House report number 94-1476)

Book of Mormon

The Book of Mormon is a sacred text of the Latter Day Saint movement, which adherents believe contains writings of ancient prophets who lived on the American continent from approximately 2200 BC to AD 421. It was first published in March 1830 by Joseph Smith as The Book of Mormon: An Account Written by the Hand of Mormon upon Plates Taken from the Plates of Nephi.

According to Smith's account and the book's narrative, the Book of Mormon was originally written in otherwise unknown characters referred to as "reformed Egyptian" engraved on golden plates. Smith said that the last prophet to contribute to the book, a man named Moroni, buried it in a hill in present-day New York, then returned to earth in 1827 as an angel, revealing the location of the book to Smith, and instructing him to translate it into English for use in the restoration of Christ's true church in the latter days. Critics claim that it was fabricated by Smith, drawing on material and ideas from contemporary 19th-century works rather than translating an ancient record.
