DNA fingerprinting used to prove paternity
DNA fingerprinting used to prove paternity. 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. The finger is pointing to one of the fathers DNA bands that matches a band in the child marked C2

EDITORS COMMENTS
This print showcases the groundbreaking technique of DNA fingerprinting being used to establish paternity. The image displays a section of an X-ray, specifically an autoradiograph, revealing distinct bands of DNA produced 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. By analyzing these patterns, scientists can definitively determine whether individuals are related. In this particular photograph, the focus lies on one specific band within the child's DNA marked C2. A finger is pointing towards it with precision and significance. This band corresponds to a matching band found in the father's genetic makeup (marked F), providing compelling evidence for their biological relationship. The implications of this scientific breakthrough extend far beyond mere curiosity or personal matters; it has immense societal impact. DNA fingerprints have revolutionized paternity testing by offering conclusive proof regarding familial connections that were previously subject to doubt or speculation. Through its intricate portrayal of molecular biology techniques like autoradiography and electrophoresis, this image encapsulates the power and potential held within genetics research and biotechnology advancements. It serves as a testament to humanity's relentless pursuit of knowledge and understanding in unraveling the mysteries encoded within our double helix structure – ultimately shaping our comprehension of life itself.
