NOTE: This video uses the term "GENE EXPRESSION." Gene expression is another term that also means Protein synthesis.  So every time the video states "Gene Expression," know that the video is referring to protein synthesis.

1. Where are the instructions to make proteins?
2. What is a gene and what does a gene code FOR?
3. Where does transcription occur? The DNA is a template used to synthesize ___________.
4. In translation, the information on mRNA is used to make _______________.
5. During transcription, DNA is used to make mRNA with the help of which enzyme?
6. Transcription occurs in 3 stages: a._____________ b._____________ c.______________
7. During initiation, what binds to the promoter region?
8. What happens to DNA upon binding of RNA polymerase to the promoter region?
9. During elongation, RNA polymerase links _____________ to ______ end of mRNA molecule.
10. Predict what signals RNA polymerase to stop transcribing the DNA molecule?
11. The pre-mRNA includes which regions?
12. What must be removed from pre-mRNA and what must be added to mRNA in order for mRNA to exit the nucleus?
13. What is a codon? Provide an example.
14. When does translation begin?
15. Who brings amino acid to the ribosome?
16. Explain how tRNA binds to the mRNA?
17. Explain how the polypeptide is elongated.
