The lac operon produces enzymes that allow the bacteria E. coli to metabolize lactose, it is in an inducable operon. When lactose is present, will the repressor protein attach or leave the operon? How would this effect the production of lactose producing enzymes?
What would happen if the operator sequence of the trp operon contained a mutation that prevented the repressor protein from binding to the operator? (Explain what would happen in both the presence and absence of tryptophan)
In the presence of lactose and the promoter sequence was mutated such that the RNA polymerase can no longer bind, the structural genes will:[ Select ] ["No longer be expressed", "Be constantly expressed", "Be deleted from the operon"] In the absence of lactose and the lacI repressor gene is mutated such that the repressor protein product can no longer bind to the operator, the structural genes will: [ Select ] ["No longer be expressed", "Be constantly expressed", "Be deleted from the operon"] In the presence of lactose and the lacI repressor gene is mutated such that the repressor protein product can no longer bind to the operator, the structural genes will: [ Select ] ["No longer be expressed", "Be constantly expressed", "Be deleted from the operon"]
When lactose is first introduced into the medium, the lac operon is not induced and thus permease isn't induced. How is it possible for lactose to enter the cell before the lac operon is induced? While the lac operon is not induced yet, lactose has many different ways to get into the cells without the need of permease. While the lac operon is not induced yet, lactose breaks down outside the cell into smaller components in order to get into the cell and then the components reassemble into lactose again inside the cell so that the induction can occur. While the lac operon is not induced yet, there is always a very high level of permease and beta galactosidase in the cell. While the lac operon is not induced yet, there is full level expression most of the time which allows a sufficient amount of permease to be expressed. This allows lactose to enter the cell. While the lac operon is not induced yet, there is low level expression most of the time which…
Operon X produces three enzymes that convert Compound A to Compound B. The R gene makes the regulatory molecule for Operon X. Normally, the three enzymes are only produced when Compound B is present. However, when the R gene is mutated (no R gene is made), none of the three enzymes are produced regardless of whether Compount B is absent or present. Is this opern inducible or repressible? Does the R gene produce an activator or repressor? Is the R protein made in an active or inactive form?
A mutation occurs in the 5′ UTR of the trp operon that reduces the ability of region 2 to pair with region 3. What will the effect of this mutation be when the tryptophan level is high? When the tryptophan level is low?
In the lac operon, the lacZ gene codes for an enzyme called ____________, which catalyze the breakdown of the sugar __________ into monosaccharides. This enzyme can also hydrolyze the sugar analog ____________, which produces blue pigments following its breakdown. Since the lac operon is not always on the bacterial cells, we add the chemical ________ which prevents the lac depressor from binding to the operators, leading to constitutive expression of the operon.
