Step 1
- Repressor: a protein that binds to a specific DNA sequence and inhibits transcription of a gene or genes. - Operator: a DNA sequence to which a repressor binds to control the expression of adjacent genes. - Allostery: the regulation of a protein's function by Show more…

a. Repressor b. Promoter c. Inducer d. Termination Sequence e. Structural Genes f. Operator g. RNA Polymerase h. Regulatory Gene i. Corepressor 1. The DNA of the Operon that is actually translated into proteins 2. The protein that can block transcription by binding to part of the operon 3. This small molecule binds to the Repressor protein to change it's shape and deactivate it 4. This enzyme does transcription by making mRNA 5. This is the endpoint for Transcription 6. This is binding site for the Repressor protein 7. This is a gene that is not in the operon but super important to the function of the operon 8. This small molecule binds to the Repressor protein to change it's shape and activates the repressor 9. The place where RNA polymerase binds to start transcription

Promoter Operator Repressor protein No transcription The above diagram shows an operon which is activated when a substrate molecule binds to the repressor causing a conformational change that subsequently dislodges the repressor from the operator site allowing transcription to occur. Describe this type of regulatory control. negative control of a repressible gene positive control of a repressible gene negative control of an inducible gene none of the above positive control of an inducible gene
