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.

The role of the signal recognition particle (SRP) in sorting proteins that contain an ER signal sequence is A. the SRP must be associated with a cytosolic ribosome before the ribosome can attach to the ER membrane and initiate translation of an mRNA encoding a protein with an ER signal B. the SRP binds the signal sequence in the cytosol after synthesis of the protein has begun on a ribosome, and escorts the ribosome/mRNA complex to the ER membrane C....

Protein C carries a mutation that causes it to have an endoplasmic reticulum signal peptide at its N-terminus, and a nuclear localization sequence at its C-terminus. In which organelle is the translated protein going to end up? Why?
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
