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....

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it produces a functional protein or it's a correct protein binding sequence) or whether the region is mutated. Select all that apply. Select all that apply. The promoter sequence is correct/functional. The repressor protein is produced. The operator sequence is correct/functional. Beta-galactosidase is produced from the lacZ gene. Permease is produced from the lacY...

The lac operon consists of a promoter that initiates
transcription of the gene i, which encodes a repressor protein. A
seperate promoter, p, within the operon initiates transcription of
z, which encodes B-galactosidase, and y, which encodes permease.
The operator, o, where the repressor protein binds to inhibit
transcription, is positioned between mutations, whereas superscript
c denotes a constitutively active mutant. The table below sea fives
the activity of B-galatosidase and permease for haploid and diploid
mutant strains. Match the...

In the lac operon, 1 codes for the repressor protein, P is the promoter which is necessary for binding RNA polymerase, O is the operator, and Z codes for the B-galactosidase. Assuming (+) denotes the wild type for a particular locus, (-) denotes a lack of a particular gene product or function, O^c is a constitutive operator, and I^s is a super repressor. Use a "+++" sign to indicate that significant quantities of functional B-galactosidase are present, a '+' sign...

In this problem you will explore how to solve problems involving partial diploid lac operon bacterial strains. Bacterial strains that are "partially diploid" have two copies of the lac operon because they aquired a plasmid carrying just the lac operon region. One copy of the lac operon region is on the recipient's bacterial chromosome, and the other copy is on the P plasmid that was introduced into the cell by conjugation. Partial diploid genotypes are written with the P segment...

The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...
