WebOperons. Although bacterial transcription is simpler than eukaryotic transcription bacteria still have complex systems of gene regulation, like operons. Operons are a cluster of different genes that are controlled by a single promoter and operator. Operons are common in prokayotes, specifically bacteria, but have also been discovered in eukaryotes. WebThe size of the OperonDB database has grown from 34 genomes in its initial release to more than 500 genomes today, and the algorithm for locating operon structures in microbial genomes has been re-designed.
