3. Name the two types of RNA and the basic function of each.
II. Protein Synthesis
List the 5 steps of protein synthesis here (use separate notes handout):
1.
2.
3.
4.
5.
6. What is ‘transcription’?
7. Where in the cell does transcription take place?
8. What are 3-base triplets of mRNA called?
9. How is it possible for an amino acid to be specified by more than one kind of codon?
10. What enzyme is involved in transcription by unzipping DNA (it’s not helicase!)?
11. Where does the mRNA go after it leaves the nucleus?
12. What is “translation”? How does it stop?
13. What are the 3-base triplets of tRNA called that complement the mRNA?
14. What is attached to the tRNA strand that is the building
block of protein?
