Bar Plot from Scientific Research

Relative strengths of common promoters and ribosome-binding site (RBS) BioBrick parts, as reported in the iGEM Registry. The number of examples of each promoter or RBS in the 301 BioBricks examined in this study are indicated above the bars ( n ). Some of these BioBricks contain multiple instances of these promoter and RBS parts. Dashed lines in ( A ) are the thresholds used to classify promoters as weak, medium, or strong.
