This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Structure and function of protein, Subject name: Biochemistry
False about signal recognition paicle ? 
Select and explain. 
A. SRP R is a docking protein, B. SRP-SRP R are GTP bound, C. Binding of signal sequence to SRP resumes translation, D. Sec 61 complex is a 3 membrane protein conducting channel
C: Binding of signal sequence to SRP resumes translation
Answer: C: Binding of signal sequence to SRP resumes translation 
Explanation: Binding of a signal sequence to SRP temporarily blocks the translation SIGNAL RECOGNITION: Signal recognition sequence originates from ribosomes & bind to SRP. This causes temporary arrest in elongation of translation. SRP guides the protein to SRP-R. SRP-ribosome -nascent protein binds to SRP-R then SRP guides the protein to SRP-R. The SRP is released from SRP-R. The ribosome binds to sec 61 complex ( translocon ), then the signal peptide gets inseed into the channel in translocon and translation resumes. Interaction of SRP - SRP-R occurs GTP hydrolysis Reference: Harper; 30th edition
