Macrophotograph of the structure of DNA: The double helical DNA molecule with a detailed view of the nucleotides. Butterfly dna. This macrophotograph is a magnified image of the structure of DNA, allowing us to view the details of the double helix and the nucleotides that make up the genetic code. The background of the image is dark, which highlights the light strands of DNA and creates a contrast that emphasizes the complexity and beauty of the DNA molecule. This image can be used for scientific, educational or medical purposes and to illustrate topics related to genetics, biology and medical research.
