Teach trp attenuation clearly with our unique model!

The trp operon consists of 5 genes the bacteria E. coli need to make the amino acid tryptophan. These genes are only switched on when tryptophan is needed by the cell. This is controlled is two ways - by a Trp repressor protein and attenuation. The Trp repressor protein is covered by our Trp Operon model and in this model we show how attenuation works.

Attenuation only happens in prokaryotic cells as transcription and translation are linked. A short peptide is made that determines if translation is fast or slow and this is used to switch on or off the tryptophan biosynthesis genes.

Buy once, print forever!

Your students will make a model of the trp attenuator and use it to see how bacteria are able to control trptophan biosynthesis genes. The model covers the trp attenuator, RNA polymerase, Trp leader protein, tRNA and ribosomes.

Compliments our Trp Operon model.
