Bacterial rRNA Operon Structure Diagram - Transcription from Promoter to Terminator #238276 (License: Personal Use)

The diagram illustrates a canonical bacterial ribosomal RNA (rRNA) operon, where the promoter sequence initiates transcription that proceeds unidirectionally toward the terminator. It includes three rRNA components-16S, 23S, and 5S-encoded as a single polycistronic transcript, later processed into mature rRNAs. The orientation is labeled 3′ at the left and 5′ at the right, indicating the direction of RNA synthesis.

Used in educational materials, textbooks, and molecular biology webpages to explain prokaryotic gene organization, transcription units, and rRNA processing; matches user intent for learning or teaching bacterial genetics.
