In yeasts, posttranslational translocation of proteins targeting the ER is
A) a process affecting many newly synthesized proteins.
B) much less common than in mammalian cells.
C) rare.
D) impossible because translocation into the ER requires the energy of protein synthesis.

Question

Quizplus · Accepted Answer

Posttranslational translocation of proteins targeting the ER in yeasts is a common process affecting many newly synthesized proteins. This is in contrast to mammalian cells where co-translational translocation is the predominant mechanism. Posttranslational translocation also occurs in bacteria and some lower eukaryotes.
