C) are very rare in E. coli
d) none of the above
A newly identified protein from the cells of the Panopyra plant on Pandora was shown to inhibit translation of its target genes by binding to the 5’ UTR of the mRNA and preventing ribosome binding. A possible way this inhibition may be relieved by an sRNA would be:
Group of answer choices
a)The sRNA acts as a silencer, suppressing the inhibitory protein and allowing translation to take place.
b)The sRNA acts as a decoy, sequestering the inhibitory protein and allowing translation to take place.
c)The sRNA acts as a marker, flagging the inhibitory protein for ubiquitination and allowing translation to take place.
You are working in the lab, with a cell-free translational system that contains
microsomes. Microsomes are artificial structures derived from pieces of endoplasmic
reticulum (ER) formed during tissue homogenization.
These microsomes lack the signal recognition particle or SRP.
You translate an mRNA that codes for a secretory protein using this system.
Which of the following outcomes do you expect?
The protein will be synthesized and its signal sequence will be removed
The protein will be synthesized and will be incorporated into the microsome
O No protein synthesis
The protein will be synthesized and will not be incorporated into the microsome

Because you have learned about the use of temperature-sensitive mutations in yeast to study protein and vesicle transport, you obtain three mutant yeast strains, each defective in some aspect of the protein secretory process. Being a good scientist, you of course also obtain a wild-type control strain. You decide to examine the fate of your GFP fusion protein in these various yeast strains and engineer the mutant strains to express your GFP fusion protein. However, in your excitement to do the experiment, you realize that you did not label any of the mutant yeast strains and no longer know which strain is defective in what process. You end up numbering your strains with the letters A to D, and then you carry out the experiment anyway, obtaining the results shown in the figure below (the black dots represent your GFP fusion protein). strain A strain B strain C strain D…arrow_forwardWhat is a possible outcome of the addition of a transcription factor such as Myod to the nucleus of a cell?

If the genes were expressed in a cell, predict which signals are preferred to be used and explain your choices. The sequence: a) C-terminal, signal for import into nucleus, signal for import into ER, N-terminal. b) C-terminal, signal for retention in ER, signal for import into mitochondria, N-terminal. c) Has signal for import into nucleus and signal for export from nucleus.arrow_forwardYou plan to synthesize a peptide to be used as a vaccine to treat melanoma, a particularly aggressive form of skin cancer. Normally, gp100, a protein on the surface of melanocytes, activates cell growth when it is bound by its ligand. Activation of the growth pathway depends on the presence of threonine in the ligand. The effective peptide vaccine will mimic the natural ligand, but won’t cause cell growth and division. Below is the sequence of the natural ligand: LDMKTAG In order to ensure your newly designed peptide vaccine does not cause cell growth upon binding, you must substitute the Threonine residue at position 5. What amino acid would you replace it with, bearing in mind that the peptide should still be similar enough to bind to the gp100 protein in the surface of melanocytes. Explain your choice. Your vaccine will be administered as a topical cream, and you require your peptide to have an overall neutral charge in order to be functional. At what pH should you formulate…arrow_forward

In the previous problem you proposed a model for how this gene could be regulated. Suppose that you carry out an experiment to test your model. To do this you cut out the regulatory sequences upstream of the gene and fuse it to a gene for green fluorescent protein (GFP). Now you can visually observe when the gene is activated. You insert this engineered gene into a host cell and look for GFP expression. You discover some mutants that have different expression levels of GFP and call them GFP1- and GFP2-. The expression levels of GFP are given below. Cell GFP expression Wild type 100 GFP1- 50 GFP2- 0 Propose an explanation for these results based on your model.
