The repressor protein for the Gal1 locus (does not / does) contain a DNA binding domain.
The repressor protein for the Gal1 locus (does not / does) contain a DNA binding domain.
Homework Answers
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.

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...
