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 gene, promoter, operator, transcription unit Promoter, operator, regulator gene, transcription unit Operator, promoter, regulator gene, transcription unit The order of the subunits does not matter, they are interchangeable What is the function of lactose in regulation of the lac operon? It is the repressor It is the inducer It is the activator It is the promoter It is the regulatory protein What is the function of lactose in regulation of the lac operon? It is the repressor It is the inducer It is the activator It is the promoter It is the regulatory protein Which of the following would increase levels of transcription in the lac operon? Lacis mutation High levels of lactose Low levels of lactose High levels of glucose Indicate whether the following lac operon genotype would produce beta-Galactosidase and Permease in the presence of lactose. Use’+’ to indicate synthesis and ‘-‘ to indicate no enzyme synthesis. Genotype beta-Galactosidase Permease lacl^+. la+cP^lacO^+. LacZ^+, lacY^+ -, – +, + +, – -, + Lac operon functions under ____ control: trp operon functions under _____ control. negative repressible: negative inducible positive inducible: negative repressible negative inducible: negative repressible negative inducible: positive repressible positive inducible: positive repressible A new operon called Terperon is discovered and is normally transcribed in the cell. It is inhibited in the presence of Rutgease. What kind of control is Terperon exhibiting? Positive repressible Positive inducible Negative inducible Negative repressible A mutation at the promoter of the regulator gene that inhibits transcription would result in the constitutive expression and transcription of a____. positive inducible operon positive repressible operon activator protien negative inducible operon Attenuation is regulated by cis acting regulatory regions of the RNA that fold in alternative structures to determine continuation of transcription. a way that is still not clearly understood. recruiting RNA polymerase II to make for point of RNA degradation and addition of polyadenylation. recruiting a Rho factor that will bind to C-rich areas of the transcribed RNA causing hairpins to form and signal for termination. Regarding the trp operon: when levels of tryptophan are low, the ___ hairpin forms, resulting in ____ of transcription. 2-3; termination 3-4; termination 2-3: continuation 3-4; continuation
