Where does a protein with a sorting signal get translated? Where does a protein without a sorting signal get translated?
In both the cases, the proteins are translated in cytoplasm itself by ribosomal machinery.
The signal itself is present on the protein once it is translated using mRNA and it specifies where the protein has to go next to get further processed or to reach its final proposed destination for which it is made. The signal sequence itself has no role in translation but after the translation.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

-How can Chimeric proteins be used to study protein sorting? - What effect would the addition of a lysosome‐targeting signal have on the subcellular localization of a. A protein that is normally cytosolic? b. A protein that is normally secreted?
Which characteristic does not pertain to miRNA? Question 9 options: a) can be translated into a protein b) cannot be translated into a protein c) complementarily binds to mRNA
An mRNA is translated into a protein in a cell-free extract in the absence of presence of microsomes or endoplasmic reticulum. Samples are treated as follows: (I) no treatment, (II) addition of protease, (IIl) addition of protease and detergent, and (IV) disruption of mircosomes and addition of endoH, an enzyme removing N-linked sugars that are added in the ER. Analysis by gel electrophoresis is shown in the figure. 7. MICROSOMESİ MICROSOMES ABSENT PRESENT TREATMENT protease a. Proteih synthesis at the...
1) What determines whether a protein will be translated in the cytosol or on the ER surface? 2) What is the difference between post-translational ER import and co-translational translocation? 3) Can you explain the steps that ensure a protein is translated in conjunction with the ER? ( Including names. What is the SRP/SRP receptor/translocon, etc, and how do they help?)
Direction of translation of cDNA, mRNA and the corresponding direction of the translated protein.
If you deleted the ER N-terminal signal sequence from a gene that encodes a protein, where would the protein end up after synthesis? (Assume no other signal sequences are present) The golgi The smooth ER The protein would be secreted from the cell The cytosol The lysosome
All RNA viruses can directly be translated into a protein. True False
Mutations in the exons of eukaryotic genes can result in changes in the translated protein. Nonexonic mutations, mutations in regions of a gene outside of the exons, can also alter the rate of transcription and the final protein. In which of the following situations would nonexonic mutations either affect expression of the gene or alter the structure of the final protein? Select all of the statements that apply.
Which of the following can be translated into protein? A. rRNA B. tRNA C. mRNA D. miRNA E. B and C
Predict where each mutant protein will go (as in, final destination), based on the set of sorting sequences it has. Hint: think about what set of sorting sequences the normal, unmutated protein would have, then think about what sorting sequences the protein would have after the changes are made. Then, figure out where a protein with these new sorting sequences would end up. - A. B. C. D. ...
