Homework Answers
Gal 4 binds to the UAS and activates the expression of the Gal1 so the answer is Gal 4.

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

you have shown that protein Abc1 (encoded by the ABC1gene) is a transcriptional activator of genes that have the upstream activation sequence of UASABC in their promoters. preliminary experiments utilizing cells expressing a fusion protein that you have constructed in which Abc1 is fused to GFP suggest that the protein has dual localization in the ER and the nucleus. you hypothesize that: a) Abc1 is tethered to the ER during repressing conditions and translocates to the nucleus during derepressing conditions;...

For Biology of Cancer- Please Explain The regulation of expression of the Ah locus, the protein products regulated by the activities of each gene, the mechanisms of AH-induced gene expression. Should be able to reason (and give an example) on how a selective or aberrant regulation of the Ah-locus might affect the predisposition to malignancies associated with exposure to AH (such as in smoking).
