E. coli Holliday junction complex C014 / 0878
E. coli Holliday junction complex. Molecular model of a RuvA protein (dark pink) in complex with a Holliday junction between homologous strands of DNA (deoxyribonucleic acid, blue and green) from an E. coli (Escherichia coli) bacterium. A Holliday junction forms during crossing over, a natural genetic process that occurs between homologous chromosomes and leads to the switching of genetic material between the chromosomes. This recombination increases the genetic variation in a population. RuvA is part of the RuvABC complex of three proteins that mediate branch migration and resolve the Holliday junction created during homologous recombination in bacteria

EDITORS COMMENTS
This print showcases the intricate E. coli Holliday junction complex, specifically the molecular model of a RuvA protein in conjunction with a Holliday junction formed between homologous strands of DNA from an Escherichia coli bacterium. The vibrant colors highlight the blue and green DNA strands, while the dark pink represents the RuvA protein. The Holliday junction depicted here is a crucial component of crossing over, a natural genetic process that occurs between homologous chromosomes. During this process, genetic material is exchanged between these chromosomes, ultimately leading to increased genetic variation within a population. RuvA plays an essential role as part of the RuvABC complex - three proteins responsible for branch migration and resolution of the Holliday junction during homologous recombination in bacteria. Its presence ensures efficient manipulation and mediation of chromosomal interactions. This visually stunning image not only emphasizes technological advancements in biology but also underscores its significance in understanding bacterial genetics and microbiology as a whole. The double helix structure symbolizes DNA's fundamental role as a carrier of genetic information. Overall, this print serves as both an educational tool and an artistic representation of complex biological processes such as recombination and gene switching mediated by bacteria like Escherichia coli – offering us glimpses into their fascinating world at the molecular level.
