A geneticist is studying an inducible operon in a species of bacteria. A regulator gene produces a repressor of the inducible operon. The geneticist isolates several constitutive mutants of this operon. Step 1: Define the terms constitutive operon and inducible operon. Where might mutations that cause the operon to be constitutively expressed ...

Science Biology Biology questions and answers Where might mutations that cause the operon to be constitutively expressed occur? How would the mutations cause the operon to become constitutive? Steps 3 and 4 illustrated several components necessary for the regulation of the inducible operon.

Question: A negative inducible operon is regulated by an inducer that inactivates a repressor. Which of the given are an example of a negative inducible operon? Lac operon RNA polymerase operon cAMP-CAP complex Glycolysis operon Trp operon In which order are the subunits of an operon arranged? Transcription unit, operator, promoter, regulator gene Regulator

Science Biology Biology questions and answers Question 27 3 pts For an enzyme to be produced from an inducible operon, the repressor must bind to and digest the substrate. the substrate must bind to the operator. the substrate must bind to the repressor and remove it from the operator. the repressor must be bound to the operator.

In a positively controlled inducible operon, the regulatory protein is synthesized as a (n) ___ Sigma factor that can be used in eukaryotes Inactive repressor Inactive activator Active activator In wild-type E. coli, in the absence of lactose and glucose, the lactose operon will ___ Degrade its RNA polymerase it can bind to the promoter of the ...

Place each of the following choices into the appropriate box to distinguish between a repressible operon and an inducible operon. Enzymes resulting from the transcription of this type of operon need only be present when a molecule, usually a nutrient, is present.

A geneticist is studying an inducible operon in a species of bacteria. A regulator gene produces a repressor of the inducible operon. The geneticist isolates several constitutive mutants of this operon.

operon is set of genes which is work and controlled by same operator there are two type of operon 1. inducible operon :- these type operon are turned off initially but, turn on in presence of small molecule like inducer which remove repress … View the full answer

Based on your understanding of the lac operon, a classic inducible operon, match the following sequence of events in order of occurrence when lactose is introduced to the environment.

Question: Compare and contrast an inducible operon and a repressible operon. Use (in the correct context) the terms promoter, operon genes, regulatory gene, repressor (active and inactive), co-repressor, operator, and RNA polymerase. Include arn example of …
