Q-2. The fate of any protein molecule synthesized in the cytosol depends on its amino acid sequence, which can contains sorting signal that directs the protein to the organelle in which it is required. TRUE OR FALSE (For extra credit, correct False statements) a. Proteins that lack a sorting signal remain permanently in the cytosol. (T/F) b. Unlike transport to the ER, directing proteins to mitochondria does not require a signal sequence. (T/F) c. Even ribosome proteins require a nuclear localization signal to enter the nucleus (T/F) d. A nuclear localization signal (NSL) is a specific kind of N-terminal Signal Sequence (T/F) e. Signal sequences are necessary and sufficient to direct a protein to the correct compartment. (T/F) 1. Import into ER and retention in the ER lumen are signated by the same hydrophobic signal sequence. (T/F) 8. Import and export to and from the nucleus requires different sequence signals. (T/F) 1. Proteins enter peroxisomes from both the cytosol and the endoplasmic reticulum (T/F)
