b. the only region of the nucleus where active transcription is occurring

c. The location in the nucleus where the RNA for membrane proteins is transcribed.

d. an area on the genome where rRNA is transcribed and located, and ribosomal subunits assemble.

e. the region inside a prokaryote where the chromosomal material would be found

3. What is the internal space of the endoplasmic reticulum called?

4. Which of the following is TRUE regarding Rough Endoplasmic Reticulum?

a.This is the region of the ER where detoxification takes place.

b. Inside the RER some newly synthesized proteins are folded and sugars are added.

c. All eukaryotic translation begins on a ribosome in the cytoplasm and then moves to the RER to complete translation there.

d. The RER is the organelle that generates vesicles destined for export from the cell surface.
