Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific ...
Life Story (known as The Race for the Double Helix in the United States) is a 1987 television historical drama which depicts the progress toward, and the competition for, the discovery of the structure of DNA in the early 1950s.

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 ...
The two strands of DNA in a double helix can thus be pulled apart like a zipper, either by a mechanical force or high temperature. [27] As a result of this base pair complementarity, all the information in the double-stranded sequence of a DNA helix is duplicated on each strand, which is vital in DNA replication.
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.
Marilyn Monroe is iconic for her blonde curls, red lips, and perfect beauty mark, but the star was shockingly unrecognizable at the time of her death. According to the two morticians, who prepared ...
The painting's title is a portmanteau of the name of Dalí's wife, Gala Dalí, and deoxyribonucleic acid (DNA). It is a tribute to Francis Crick and James D. Watson, who are credited with determining the double helical structure of DNA in 1953. The painting is in the collection of the Salvador Dalí Museum in St. Petersburg, Florida. [1]
