Protein Insertion into the Mammalian ER Membrane is Typically

Question

Protein insertion into the mammalian ER membrane is typically:
A)cotranslational.
B)post-translational.
C)pretranslational.
D)quasitranslational.

Accepted Answer

Protein insertion into the mammalian ER membrane is typically cotranslational, meaning that it occurs during the process of translating the protein from RNA. This allows for proper folding and modification of the protein as it enters the ER lumen.
