DNA fingerprinting, sequence of bases
Conceptual computer artwork of DNA fingerprinting used to prove family relationships. The illustration is based on a sequence of bases in a fragment of DNA (deoxyribonucleic acid), part of an autoradiograph of bands of DNA produced by the technique of electrophoresis. The pattern of these DNA 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. This illustration shows the sequence graphics rearranged to display the letters DNA. 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. Genetic fingerprinting and DNA profiling was developed by Dr. Alec Jeffreys and his team in 1985

EDITORS COMMENTS
This print showcases the intricate world of DNA fingerprinting, a groundbreaking technique used to establish family relationships. The conceptual computer artwork is based on a sequence of bases found in a fragment of DNA, specifically captured through the electrophoresis method and displayed as an autoradiograph. Each individual possesses a unique pattern of DNA bands, but certain bands are shared among relatives like parents and children. These distinct DNA fingerprints provide conclusive evidence for determining familial connections. The arrangement of the sequence graphics in this illustration forms the letters "DNA" symbolizing the fundamental building blocks that make up our genetic code. It pays homage to James D. Watson and Francis Crick's revolutionary double-helix model, first published in 1953 after Rosalind Franklin's pivotal X-ray diffraction image known as "Photo 51" from 1952. Dr. Alec Jeffreys and his team further advanced genetic fingerprinting and DNA profiling in 1985, paving the way for modern applications in forensic science and paternity testing. This artful representation not only highlights their significant contributions but also serves as a reminder of how biochemistry intertwines with biology to unravel the mysteries encoded within our genes. Through its mosaic-like composition, this print encapsulates both scientific precision and artistic beauty while shedding light on one of humanity's most remarkable discoveries – our ability to decipher our own genetic material through nucleotides, nucleic acids, genes, genetics, and ultimately uncover profound truths about ourselves and our kinship ties.
