Eukaryotic cells manufacture cytoskeletal proteins that help to maintain the cells' shapes and functions. What would you predict about these proteins?
A) They would be manufactured on free ribosomes in the cytoplasm.
B) They would be glycosylated in the Golgi apparatus.
C) They would initially contain signal sequences that would allow their entrance into the endoplasmic reticulum.
D) They might travel to the nucleus in a transport vesicle with a specific zip code.

Quizplus · Accepted Answer

Cytoskeletal proteins, which are involved in maintaining cell shape and structure, are typically synthesized on free ribosomes in the cytoplasm, not on ribosomes attached to the endoplasmic reticulum, which are involved in the synthesis of proteins destined for secretion or for use in the cell membrane or certain organelles.
