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.

Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
