Microtubes, pipettor (pipette) tip & DNA sequence
DNA research. View of the tip of a pipettor (upper left), a type of automatic pipette, and microtubes in a rack on top of a DNA sequence. The DNA sequence, which is also known as an autoradiogram, is four rows of irregularly spaced black bands. A DNA sample can be taken from body fluids and tissues. The DNA is then fragmented with enzymes and arrayed by size by electrophoresis (separation under an electric field). The banding pattern is then exposed onto an X-ray film. The bands represent the positioning of the base pairs (cytosine-guanine and adenine- thymine) on the DNA chain. This makes up the genetic code which is unique to every person

EDITORS COMMENTS
This print captures the intricate world of DNA research. In the upper left corner, we see the tip of a pipettor, an automatic pipette used in scientific laboratories. The focus then shifts to a rack of microtubes delicately arranged on top of a DNA sequence. This autoradiogram showcases four rows of irregularly spaced black bands that represent the positioning of base pairs on the DNA chain. The process behind this image is fascinating. A DNA sample is extracted from body fluids and tissues before being fragmented with enzymes and sorted by size through electrophoresis under an electric field. The resulting banding pattern is then exposed onto an X-ray film, revealing the unique genetic code present in every individual. This still life composition beautifully combines elements from biochemistry, genetics, and biotechnology to highlight the significance of DNA analysis in scientific research. It serves as a visual reminder that within these microscopic strands lies our very essence - our genetic makeup that distinguishes us from one another. Science Photo Library has once again captured the beauty and complexity inherent in scientific exploration with this stunning portrayal of molecular biology at its finest.
