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....

please answer both
Which of the following is NOT TRUE regarding both M6P and KDEL receptors? Select one: a. They help transport cargo to their proper destinations b. They bind to cargo proteins in the Golgi apparatus. c. They are transported by vesicle budding and fusion, d. They move back-and-forth between different organelles. O e. They release soluble cargo proteins at lower pH. Which of these is NOT a function of the Signal Recognition Particle (SRP) involved in transport of...
