DNA molecules contain the code for the properties of an organism. These images were created by Frederick Sanger, who devised a method for determining the genetic code. More precisely, the sequence of nucleotides in DNA is determined by reading the bands in the picture.
The photographs were presented to the Nobel Prize Museum in 2017 by Richard Henderson, chemistry laureate this year. Sanger and Henderson were both affiliated to the MRC Laboratory of Molecular Biology in Cambridge, UK.
