B) Endoplasmic reticulum
C) Golgi apparatus
D) Nucleus

Question

Quizplus · Accepted Answer

Proteins that are destined for export from the cell or that are inserted into the lipid bilayer are synthesized on the endoplasmic reticulum, which is responsible for protein synthesis and modification before export or insertion into the membrane. Free ribosomes synthesize proteins that will remain inside the cytoplasm of the cell. The Golgi apparatus is responsible for further modification and sorting of proteins before they are shipped out of the cell. The nucleus is responsible for DNA replication and transcription.
