Answer #1

The statement is False.

It is because the gene expression in prokaryotes is regulated by transcription. When a protein is needed, the level of transcription increases and it is based on the activity of activator and repressor; and not the promoter.

Hope it helps, Good luck

    What control elements regulate expression of the mPGES-1 gene? The promoter of a gene includes the DNA immediately upstream of the transcription start site, but expression of the gene can also be affected by control elements. These can be thousands of base pairs upstream of the promoter, grouped in an enhancer. Because the distance and spacing of these control elements make them difficult to identify, scientists begin by deleting sections of DNA that contain possible control elements and measuring the...

    1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

    You are conducting an experiment identifying enhancers that regulate the expression of a gene that codifies for a protein that participates in cell division. The gene is called Mitosis Regulatory Protein A or MRPA. The complete DNA sequences for the MRPA promoter and coding region have been identified. However, it is unknown if MRPA has enhancers regulating its transcription. To answer this question your lab first produced a transgenic cell line where GFP has been inserted as a reporter gene....

    Question 2 You construct a reporter gene for the NF-kB pathway consisting of a promoter to which NF-kB can bind, upstream of a series of MS2 repeats and a lacZ gene sequence. You integrate this reporter at a single locus in the genome of a mammalian cell line, and co-express MCB-GFP in these cells. You then treat these cells with either a control solution or TNF-a ligand, and record the following fluorescence intensities in nuclear spots. In both cases, 100%...
