You discover and describe an enzyme that works in the cytosol of E.coli to increase the stability of the mRNA of a structural gene.

Would this affect the transcription or translation of a gene? (i think translation??)

Would you expect more or less protein produced? (more i think??)

7. In a mutant eukaryotic cell, the proteins involved in the addition of the 5’ cap of mRNA have been inactivated. Explain if this would affect the following and why it does (or doesn’t). a) The export of the mRNA from the nucleus to the cytosol?

b) Assuming the mRNA is in the cytosol, would this affect its translation?

Which are the factors that modify the overall gene differentialexpression by introducing a vector for single-geneoverexpression?

If you overexpress a gene for a protein involved in signaltransduction (e.g., a kinase, scaffold, or receptor) by vector celltransfection, then you overdrive the cell using this signalingpathway, it's useful to isolate the pathway and study them.

Is there any way to modify the overall gene expression or celldifferential expression pattern by gene transfection? I think thiswould work if you delivered a gene for overexpression in proteinsinvolved for RNA processing (e.g., splicing, ribosomal proteins,etc.), RNA transcription (e.g., TFs) or protein translation.

Please answer thoroughtly.

You are analyzing an unknown gene that is expressed robustly under certain conditions. You have sequenced the gene and in the 5' UTR of the mRNA you find the following sequence: 5'-CGCCGCCGCCGCCGC-3' Between this sequence and the start codon there is a stretch of nucleotides that could form a stem-loop that would prevent either transcription or translation (but you are not sure which).

A) What signal do you think this 5' UTR is designed to sense?

B) Why might that signal occur? Name the molecules involved.

C) What might be the product of your unknown gene?
