Random information on the term “DNA”:

An autosome is a chromosome that is not an allosome (a sex chromosome). Autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas members of an allosome pair may differ from one another and thereby determine sex. The DNA in autosomes is collectively known as atDNA or auDNA.

For example, humans have a diploid genome that usually contains 22 pairs of autosomes and one allosome pair (46 chromosomes total). The autosome pairs are labeled with numbers (1–22 in humans) roughly in order of their sizes in base pairs, while allosomes are labelled with their letters. By contrast, the allosome pair consists of two X chromosomes in females or one X and one Y chromosome in males. (Unusual combinations of XYY, XXY, XXX, XXXX, XXXXX or XXYY, among other allosome combinations, are known to occur and usually cause developmental abnormalities.)

Autosomes still contain sexual determination genes even though they are not sex chromosomes. For example, the SRY gene on the Y chromosome encodes the transcription factor TDF and is vital for male sex determination during development. TDF functions by activating the SOX9 gene on chromosome 17, so mutations of the SOX9 gene can cause humans with a Y chromosome to develop as females.

Random information on the term “RNA”:

Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function. The structure of these molecules may be considered at any of several length scales ranging from the level of individual atoms to the relationships among entire protein subunits. This useful distinction among scales is often expressed as a decomposition of molecular structure into four levels: primary, secondary, tertiary, and quaternary. The scaffold for this multiscale organization of the molecule arises at the secondary level, where the fundamental structural elements are the molecule’s various hydrogen bonds. This leads to several recognizable domains of protein structure and nucleic acid structure, including such secondary-structure features as alpha helixes and beta sheets for proteins, and hairpin loops, bulges, and internal loops for nucleic acids.

The terms primary, secondary, tertiary, and quaternary structure were introduced by Kaj Ulrik Linderstrøm-Lang in his 1951 Lane Medical Lectures at Stanford University.

Random information on the term “RNAS”:

Captain Sir John (‘Jack”) William Alcock KBE DSC (5 November 1892 – 18 December 1919) was a Royal Navy and later Royal Air Force officer who, with navigator Lieutenant Arthur Whitten Brown, piloted the first non-stop transatlantic flight from St. John’s, Newfoundland to Clifden, Connemara, Ireland. He died in a flying accident in France in 1919.

John Alcock was born on 5 November 1892 at Basford House on Seymour Grove, Firswood, Manchester, England. He attended St Thomas’s Primary School in Heaton Chapel, Stockport and Heyhouses School in Lytham St Annes. He first became interested in flying at the age of 17. His first job was at the Empress Motor Works in Manchester. In 1910 he became an assistant to Works Manager Charles Fletcher, an early Manchester aviator and Norman Crossland, a motor engineer and founder of Manchester Aero Club. It was during this period that Alcock met the Frenchman Maurice Ducrocq who was both a demonstration pilot and UK sales representative for aero engines made by the Italian Spirito Mario Viale.
