Teach gene regulation with our easy to make model!
The trp operon consists of 5 genes the bacteria E. coli need to make the amino acid tryptophan. The genes make the proteins needed for 3 enzymes. These genes are on by default but switched off when tryptophan is present to save energy.
Buy once, print forever!
Your students will make a model of the trp operon and use it to see how bacteria are able to control these genes. The model covers the trp repressor, RNA polymerase, operator, promoter and the trpA, trpB, trpC, trpD and trpE genes and their products.
Great to compare and contrast with our lac operon model!
