Here the figure depicts recombinant proteins with various types of signal sequences.
Here the final cellular destination of each protein is shown in image- 'B' because mRNA comes to the cytoplasm of the cell from the nucleus through ER and then protein synthesis occurs in the cytoplasm. So, the "nucleus import sequence" and "ER import sequence" must be present there.

2 After isolating the rough endoplasmic reticulum from the rest of the cytoplasm, you purify the RNAS attached to it. Which of the following proteins do you expect the RNA from the rough endoplasmic reticulum to encode? (a) (c) soluble secreted proteins plasma membrane proteins ER membrane proteins all of the above (b) (d) -13 In which cellular location would you expect to find ribosomes translating MRNAS that encode ribosomal proteins?

For her research project, Anneka found this great website to predict the transmembrane domains of secretory proteins. An algorithm allows estimating the hydrophobicity of amino acid stretches in the sequence of secretory proteins. Hydrophobic stretches are plotted with positive values on the Y-axis. On the X-axis, Anneka can see the protein sequence expressed as amino acid number, with N-terminus at the intersection with the Y-axis. Example of prediction of TMD domains (a) Human growth hormone receptor (type 1) Nw Signal...
