DNA fingerprinting for proving family relationship
DNA fingerprinting used to prove family relation- ships. The photo shows part of an X-ray (or autoradiograph) of bands of DNA produced by the technique of electrophoresis in an agarose gel. 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. The bands in these DNA fingerprints are marked M for mother, C for child, F for father. In this case, the mothers bands have been marked in red, the fathers in blue. Both children share some bands with each parent, proving that they are indeed related

EDITORS COMMENTS
The captivating print showcases the fascinating world of DNA fingerprinting, a groundbreaking technique used to establish family relationships. The image captures an X-ray or autoradiograph that reveals distinct bands of DNA created through electrophoresis in an agarose gel. Each individual possesses a unique pattern of these DNA bands, but some are shared among relatives, such as parents and children. In this mesmerizing snapshot, we witness the power of DNA fingerprints to conclusively prove familial connections. The marked bands on the autoradiograph indicate the presence of genetic material from different family members: red for the mother's bands and blue for the father's. Remarkably, both children exhibit shared bands with each parent, providing irrefutable evidence that they are indeed related. This photograph epitomizes the intersection between biology, chemistry, genetics, and cutting-edge biotechnology. It symbolizes humanity's relentless pursuit of knowledge in unraveling our genetic code and understanding our origins at a molecular level. DNA sequencing and paternity testing have revolutionized forensic science by enabling accurate identification of individuals based on their unique genetic profiles. Science Photo Library has masterfully captured this pivotal moment in scientific history through this visually stunning image – a testament to mankind's quest for truth within our own double helix structure.
