Explaination: here Oc is a constitutive operator means expression of operon in both presence or absence of inducer because here mutation in operotor gene which prevent the binding of repressor with operator and hence RNA polymerase binds to promoter and operon expression continues.

PLEASE note that there may be (most likely be) more than one number that satisfies the answer. For example, for the first question, #1 may not be the only answer. PLEASE LIST ALL NUMBER THAT CORRESPONDS ISP+OCZ+Y+ For this genotype, indicate whether the enzyme is indicated is produced at significant levels. 1 ?-galactosidase, no lactose present 2 ?-galactosidase, lactose present as sole carbon source 3 permease, no lactose present 4 permease, lactose present as sole carbon source To enter your...

For each genotype, with and without inducer, select whether or not a functional galactosidase or permease will be present. IS indicates a super-repressor (it can’t bind to lactose/inducers). OC indicates a constitutive operon (no repressor can bind to this region of DNA). I- ; Z- ; Y- each indicate an allele that does not produce a functional protein. P- indicates a mutation in the promoter region such that RNA polymerase does not bind. Group of answer choices I+ P+ O+...

A number of mutations affect the expression of the lactose operon in E. coli. Complete the table given below. Use a + to indicate that the enzyme is synthesized at greater than basal levels, and a 0 to indicate that the enzyme is not synthesized. Assume glucose is NOT present. Lactose Present B-galactosidase Permease Lactose Absent B-galactosidase Permease (a) I+O+Z+Y+ (b) 1 O+Z+Y+ (c) 1-O+Z+Y+ (d) I+0 Z+Y+ (e) I OʻZ+Y- (f) I+0 Z+Y-/ F'1-O+Z- Y+ (g) I+P+O+Z-Y+/ F' I+P-OZ+Y-...

The lac operon in E. coli is a well-studied gene system, and
β-galactosidase (β-gal) is the product of the lacZ gene. The
diploid conditions represent the addition of a plasmid carrying
different components of the lac operon. Determine if β-gal will be
generated under the conditions. Assume that glucose is absent. A +
in the genotype indicates a functioning gene, while a – indicates a
loss-of-function allele. The OC is an operator mutant that cannot
bind the lacI protein. Use...

Complete the table below using to indicate if the enzyme is synthesized and to indicate if the enzyme will not be synthesized. Genotype symbols: Ilacl (the repressor gene): P=Pac (the promoter), O = laco (the operator). Z = lacZ (the B-galactosidase gene), and Y lacy (the permease gene). The minus sign accompanying the symbol (0.g. 1) indicates a mutant gene, the plus sign indicates wild-type/functional gene. O is the constituitive operator mutation (the same as O-) and...

An E. Coli strain possesses the following genotype: F(P+)/" pCo+z+y+ where l' is a mutation that eliminates the production of repressor and PC eliminates the ability of the polymerase to bind the promoter. The structural genes will be transcribed both in the presence and absence of lactose O will be transcribed only if lactose is absent O will be transcribed only if lactose is present will not be transcribed under any onditions will be transcribed but not translated

1. The map of the lac operon is P-O-Z-Y. The promoter (P) region is the start site of transcription through the binding of the RNA polymerase molecule before actual mRNA production. Mutationally altered promoters (P-) apparently cannot bind the RNA polymerase molecule. Certain predictions can be made about the effect of p-mutations, Use your knowledge of the lactose system to complete the following table. Insert a "4" where an enzyme is produced and a "_" where no enzyme is produced....
