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]
Ancient DNA from bubonic plague victims buried in cemeteries on the old Silk Road trade route in Central Asia has helped solve an enduring mystery, pinpointing an area in northern Kyrgyzstan as ...
The DNA double helix was discovered in 1953 [4] (with further details in 1954 [5]) based on X-ray diffraction images of DNA (most notably photo 51, taken by Raymond Gosling and Rosalind Franklin [6]) as well as base-pairing chemical and biochemical information.
DNA from human remains found in a medieval well suggests they belonged to Ashkenazi Jews who fell victim to antisemitic violence during the 12th century. ... likely caused by being deposited head ...
Bind to ssDNA and prevent the DNA double helix from re-annealing after DNA helicase unwinds it, thus maintaining the strand separation, and facilitating the synthesis of the new strand. Topoisomerase: Relaxes the DNA from its super-coiled nature. DNA gyrase: Relieves strain of unwinding by DNA helicase; this is a specific type of topoisomerase ...
Ancient DNA recovered from Pompeii shows that people found holding one another beneath the volcanic ash weren’t related in the ways we think. DNA analysis upends long-held assumptions about ...
The cranium was fully intact including all of its teeth from the time of death. [10] All major bones were found except the sternum and a few in the hands and feet. [11] After further study, Chatters concluded it was "a male of late middle age (40–55 years), and tall (170 to 176 cm, 5′7″ to 5′9″), and was fairly muscular with a slender build". [10]
The data suggested that the unstretched fibres had a coiled molecular structure with a characteristic repeat of 5.1 Å (=0.51 nm). Astbury proposed that (1) the unstretched protein molecules formed a helix (which he called the α-form); and (2) the stretching caused the helix to uncoil, forming an extended state (which he called the β-form).
