RNA & Transcription

Where does Transcription take place?

• Inside the nucleus

• Inside the cytoplasm

• Inside the Ribosome

• Inside the Rough ER

During protein synthesis, an RNA strand is transcribed from one strand of DNA (GCG TTA CCT) What is the complementary RNA strand?

What happens to the mRNA sequence after it has been synthesized?

• stays in the nucleus

• leaves the cell

• leaves the nucleus

• separates into smaller pieces
