What is an aporepressor?

An aporepressor is a repressor which binds with a corepressor.


The role of a metabolite that controls a repressible operon is to?

Function as a corepressor that binds to the repressor protein and activates it to bind to the operator region of the operon. This binding prevents RNA polymerase from transcribing the operon genes, leading to the downregulation of gene expression.


If a particular operon encodes enzymes for making an essential amino acid and is regulated like the trp operon then will the amino acid act as a corepressor?

Yes, in the case of an operon encoding enzymes for making an essential amino acid and regulated like the trp operon, the amino acid would act as a corepressor. When the levels of the amino acid are sufficient, it can bind to the repressor protein, allowing it to bind to the operator region of the operon, thereby blocking transcription of the genes involved in amino acid biosynthesis.


What acts as a co-repressor to block transcription of the tryptophan operon?

The corepressor tryptophan itself binds to the repressor protein, causing a conformational change that allows it to bind to the operator sequence of the tryptophan operon. This blocks RNA polymerase from transcribing the operon, leading to repression of tryptophan biosynthesis.


The tryptophan operon is a repressible operon that is?

regulated by the availability of tryptophan. When tryptophan levels are high, tryptophan acts as a corepressor, binding to the repressor protein, which then binds to the operator, preventing gene transcription. This allows bacteria to conserve energy by only producing tryptophan when needed.


The tryptophan synthetase operon uses glucose to synthesize tryptophan Repressible operons such as this one are?

typically involved in anabolic pathways that synthesize essential molecules. When the end product is abundant, it acts as a corepressor to inhibit transcription. This regulatory mechanism ensures that resources are not wasted on unnecessary synthesis.


What non protein molecule would result in the ability of the cell to turn off genes?

Small interfering RNA (siRNA) is a non-protein molecule that can result in the ability of the cell to turn off genes. siRNA binds to complementary messenger RNA (mRNA) molecules, leading to their degradation and preventing translation into protein, effectively silencing gene expression.
