QUESTION 38
What is responsible for degrading misfolded proteins in the cytoplasm?
OA. Peroxisome
B.
Proteosome
OC. Endosome
O D. Lysosome
QUESTION 39
What is the primary function of molecular chaperones?
OA. They transport secretory proteins into secretory vesicles.
OB. They bind to glycosylases to assist in proper protein glycosylation in the Golgi.
OC. They bind only to misfolded proteins to help them obtain their proper tertiary structure.
OD. They bind proteins only after translation is complete to help them to fold into their proper primary structure.
O E. They bind to unfolded or misfolded RNAs and help them attain their proper tertiary structure.
QUESTION 40
Which sequence(s) would a protein need to be translated, targeted to the ER, and retained in the ER as an ER-resident protein?
A. signal peptide sequence and KDEL sequence
OB. Nuclear localization signal and signal peptide sequence
OC. Nuclear localization signal and KDEL sequence
OD. Signal peptide
