The activator protein of the Gal1 locus is called ____________.
The activator protein of the Gal1 locus is called ____________.
Homework Answers
Gal 4 binds to the UAS and activates the expression of the Gal1 so the answer is Gal 4.
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.

How is the activation of the GAL1 gene prevented in the presence of glucose? The presence of glucose leads to binding of the Mig1 protein to DNA. Mig1 forms a complex with the co-repressor protein Gal4. Gal4 acetylates histones near the GAL1 gene, which shuts down transcription. The presence of glucose leads to binding of the Mig1 protein to DNA. Mig1 forms a complex with the co-repressor protein Tup1. Tup1 deacetylates histones near the GAL1 gene, which shuts down transcription....

Consider an E. coli strain carrying a mutation in crp (encoding the catabolite activator protein) that prevents CAP from binding CAMP. Predict whether the repressor and the activator is active (able to bind to DNA) or inactive (unable to bind to DNA), and the level of transcription in the following scenarios. Options for transcription levels include high, medium, leaky and off. a. When lactose is present but glucose is not, the repressor is and the activator is leading to levels...

You have identified a novel activator protein. You assume that
like other activators, your protein has activation and DNA binding
domains. You carry out deletion analysis on the part of the ORF
that codes for the C-terminal end of your activator and assay both
DNA binding and transcription. You obtain the results indicated in
the figure below. Answer the following 3 parts (i,ii, &
iii) based on this information.

The LacI protein is released from the operator sequence upon binding of IPTG, allowing the transcription of all the genes within the lac operon. In this case, LacI is called a transcriptional _______. In comparison, CRP binds to the CRP binding site sequence upon binding of cAMP, enhancing transcription. CRP is called a transcriptional _______. Select one: a. activator ;;;;; activator b. activator ;;;;; repressor c. repressor ;;;;; activator d. repressor ;;;;; repressor e. None of these
