Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) [ 1] was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. [ 2] Although her works on coal and viruses were appreciated in her lifetime ...
The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. Translation is accomplished by the ribosome , which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA ...
is a song from Chappell Roan's 2023 album, THE Rise and Fall of a Midwest Princess. To promote the song, Chappell Roan created a dance for the song's chorus that spells out the song's title with a ...
The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling, [2] [3] a postgraduate student working under the supervision of Maurice Wilkins and Rosalind Franklin at King's College London, while working in Sir John Randall's group.
The search for extraterrestrial intelligence ( SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets. [ 1][ 2][ 3] Scientific investigation began shortly after the advent of radio in the early ...
Studies using direct DNA analysis are now abundant and may use mitochondrial DNA (mtDNA), the non-recombining portion of the Y chromosome (NRY), or even autosomal DNA. MtDNA and NRY DNA share some similar features, which have made them particularly useful in genetic anthropology.
