When the fungal metabolite brefeldin A is added to cells, the
Golgi apparatus largely disappears and the Golgi proteins intermix
with those in the ER. Brefeldin A treatment also causes the rapid
dissociation of some Golgi-associated peripheral membrane proteins,
including subunits of the COPI coat. This implies that brefeldin A
prevents transport involving COPI-coated vesicles by blocking the
assembly of coats and thus the budding of transport vesicles. In
principle, brefeldin A could block formation of COPI-coated
vesicles at any...

What is the difference between a nuclear envelope and a plasma membrane? A nuclear envelope is made of two membranes, while the plasma membrane is a single membrane. A nuclear envelope does not contain membrane proteins, while the plasma membrane contains membrane proteins. There is no difference between a nuclear envelope and a plasma membrane A nuclear envelope allows water and gases to pass freely, while the plasma membrane does not. Which of the following is not a membrane-bound organelle?...
