E. coli Holliday junction complex
E. coli Holliday junction complex. Molecular model of a RuvA protein (red) in complex with a Holliday junction between homologous strands of DNA (deoxyribonucleic acid, brown and orange) 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, a molecular model that represents the fascinating process of genetic recombination. In this image, we see a RuvA protein (depicted in red) interacting with a Holliday junction formed between homologous strands of DNA (colored in brown and orange). The DNA strands belong to an Escherichia coli bacterium, commonly known as E. coli. Crossing over is a natural genetic phenomenon that occurs between homologous chromosomes during reproduction, allowing for the exchange of genetic material between them. This crucial process leads to increased genetic variation within populations. RuvA plays a vital role as part of the RuvABC complex, which consists of three proteins responsible for mediating branch migration and resolving the Holliday junctions created during homologous recombination in bacteria. Its presence ensures proper manipulation and mediation of chromosomal interactions. The black background enhances the visual impact of this molecular structure, highlighting its complexity and significance in biology and genetics. The image also emphasizes scientific advancements through technology by showcasing how DNA can be manipulated and combined to study various biological processes. Overall, this print from Science Photo Library provides an intriguing glimpse into the world of microbiology and genetic engineering while shedding light on essential concepts such as crossover, recombination, genes, chromosomes, and their interplay within bacterial organisms like E. coli.
