Watson and Crick with their DNA model Featured DNA Print

Watson and Crick with their DNA model

^BCOMMERCIAL USE REQUIRES CLEARANCE.^bThe discoverers of the structure of DNA. James Watson (b.1928) at left and Francis Crick (1916-2004), with their model of part of a DNA molecule in 1953. Crick & Watson met at the Cavendish Laboratory, Cambridge, in 1951. Their work on the structure of DNA was performed with a knowledge of Chargaff's ratios of the bases in DNA and some access to the X-ray crystallography of Maurice Wilkins and Rosalind Franklin at King's College London. Combining all of this work led to the deduction that DNA exists as a double helix. Crick, Watson and Wilkins shared the 1962 Nobel Prize for Physiology or Medicine, Franklin having died of cancer in 1958. Photographed in the Cavendish Laboratory, University of Cambridge, UK, in May 1953

DNA Double Helix with Autoradiograph

Conceptual computer illustration of the DNA double helix together with a graphic representation of an autoradiograph display. The pattern of the DNA autoradiograph bands is unique to each individual, but some bands are shared by related people, such as a parent & child. DNA fingerprints can be used to prove conclusively whether people are related. The double-helix model of DNA structure was first published in the journal Nature by James D. Watson and Francis Crick in 1953, based upon the crucial X-ray diffraction image of DNA labeled as "Photo 51", from Rosalind Franklin in 1952. The structure of a double-helix elucidated the mechanism of base pairing by which genetic information is stored and copied in living organisms. Genetic fingerprinting and DNA profiling was developed by Dr. Alec Jeffreys and his team in 1985

Transcription factor and DNA molecules

Transcription factor and DNA molecules. Molecular model showing the secondary structure (helices) of the transcription factor Brachyury (purple) binding to a molecule of DNA (deoxyribonucleic acid, running horizontally from left to right). Brachyury, also known as T, is a protein that controls the transcription of DNA to RNA (ribonucleic acid) by the enzyme RNA polymerase. RNA is the intermediate product in the formation of a protein from its gene. Brachyury binds to a specific sequence of bases in the DNA called a T-box. Brachyury has been found to be crucial in embryonic development in animals. It is necessary to form the mesoderm, the precursor tissue that eventually develops into the internal organs and bones
