The repressor protein for the Gal1 locus (does not / does) contain a DNA binding domain.
expression of GAL 1 gene is activated by the Gal 4 protein it binds to the UAS and activates the expression of the Gal genes, but Gal 80 is the inhibitor of the Gal genes it inhibits the Gal4 by binding to it and prevents its binding to the DNA , the repressor protein, Gal 80 binds to the activator protein and not to the DNA.
The repressor protein for the Gal1 locus does not contain a DNA binding domain
The repressor protein for the Gal1 locus (does not / does) contain a DNA binding domain.
The activator protein of the Gal1 locus is called ____________.
The lac repressor active site The active site of the lac repressor protein is composed of OK Multiple Choice Inces O the protein domain that binds to allolactose. the protein domain that binds to DNA the protein domain that binds to other lac repressors O a glucose binding domain < Prev
Fill in the blank (7pts) 5. Histone is a linker histone that can affect nucleosome packing. 6. The p in the CpG motif refers to 7. The yeast Gall gene is regulated by trans-acting activators and repressors. The repressor protein is called 8. The activator protein of the Gall locus is called 9. The repressor protein for the Gall locus (does not / does) contain a DNA binding domain. 10. Deamination of cytosine results in 11. Deamination of 5-methyl cytosine...
How is the DNA-binding behavior of polymerase similar to that of the lac repressor?
1. If tryptophan interacts with a repressor protein (which it does in real life) and the trp operon is anabolic (which it is) a. What would happen to tryptophan production levels and energy expenditure in a mutant bacterial cell that had a repressor protein that was incapable of binding to tryptophan (but was normal in every other way) b. What would happen to tryptophan production levels and energy expenditure in a mutant bacterial cell that had a repressor protein that...
(2) In isolation, a DNA-binding protein binds to its regulatory sequence with a Kd of 1.0 M. Another DNA binding protein binds to another sequence on the same DNA a few bases away with a Kd of 5.0 HM when alone. The two proteins each have a domain which binds to the other with an interaction energy of -2.7 kcal/mole: (a) Draw the thermodynamic box which represents all four states of this system (b) what are the affinities for each...
Review Each temperate (or lysogenic) bacteriophage (e.g., lambda, 434, P22) encodes its own repressor protein. The repressor binds to six binding sites within the phage genome. These sites can also be bound by a second transcriptional repressor encoded by the phage, called Cro. The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenicaly. Launch the molecular model of the temperate bacteriophage repressor to explore its structure. Then, answer the questions. Launch...
if expression of a gene is regulated by stopping a repressor protein from binding to an operator, transcription could also be described as affected by 01. Negative control 2. Induction 3. Positive control 1. Repression
e ansecey e 7. If an abnomal repressor protein could still bind allolactosc, but the binding of allolactose did not alter the conformation of the repressor protein, how would this affect the expression of the lac operon? Weeld th
