Work through the chapter 17 lecture highlights. There are practice examples for parts of this assignment. Read the corresponding sections in the textbook chapter.

Directions- show your work on the first page

1. Label the template and coding strand. Label upstream and downstream ends.

2. On the template strand identify the promoter.

3. Identify the start site.

4. Block off and number the triplets to be transcribed.

5. Create the pre-mRNA. Label 5’ and 3’ ends.

6. Using the codon table for mRNA (genetic dictionary), identify the start and stop codons.

7. Identify the utrs (untranslated regions).

8. Add a 5’ cap to the 5’ end of the mRNA transcript and a poly-A-tail to the 3’ end.

9. Block off and number codons that can be translated into amino acids.

10. Codon 7 is an intron. Remove it.

11. Using the codon table for mRNA, translate remaining exons. Add an amino and carboxyl group to the appropriate ends of the polypeptide in its primary structure.
