Question

The term "repressible" refers to a system in which the production of a gene product is repressed in the presence of a specific molecule. The trp operon, which regulates the production of tryptophan in bacteria, is an example of a repressible system. When tryptophan is present in the environment, it acts as a corepressor and binds to the repressor protein, causing it to bind to the operator and block transcription of the genes in the trp operon. As a result, the phenotype of the trp operon is repressed in the presence of tryptophan, making F the correct choice.
