Protein Synthesis

In what process is mRNA synthesized?

• Transcription

• DNA Replication

• Translation

• Mitosis

Where does transcription occur?

• Cytoplasm

• Nucleus

• Ribosome

• Mitochondria

Why must transcription occur where DNA can be found?

• Ribosomes are in the nucleus

• Helicase unzips the DNA

• DNA cannot leave the nucleus

• DNA polymerase is found there
