Plasmid Vector Diagram: Promoter, Gene of Interest, and Kanamycin Resistance #3738378 (License: Personal Use)

This diagram illustrates a common bacterial expression plasmid with three core components: a promoter region (orange arrow) driving transcription of the gene of interest (green arc), and a kanamycin resistance gene (KanR, gray arc) serving as a selectable marker. The circular layout reflects the physical structure of plasmid DNA, with directional arrows indicating transcriptional orientation. Such maps are foundational in genetic engineering for designing and verifying cloning strategies.

Used in molecular biology educational resources, lab protocols, and biotechnology product documentation; supports users learning or implementing plasmid-based gene cloning, transformation, and selection.
