Please answer questions 12, 13, and 14. The table has already been filled in. Thank you!

The sequence elements listed in the left column are important for gene expression (some only in eukaryotes). Complete the table. For "Sequence", write in the actual conserved sequence (see example below). For "Position within the gene'", write in where the sequence element is found relative to the following gene features: promoter, coding exons, 5' UTR, 3' UTR or introns. Use words like upstream, downstream, 5' and 3' to specify position. Name of the Sequence Position within the gene Sequence i.e. TATA cC Proximal Promoter Start codon 5" splice site 3 splice site Stop codorn Cleavage and Polyadenylation Sequence GU-rich sequence (required or cleavage) Poly A tail tra rll GU-rich nt 12.

Some or all of the sequence elements listed above are found in the pre- mRNA sequence (transcribed region prior to splicing). Which ones (provide names)? 14. Some or all of the sequence elements listed above are found in the mRNA sequence (after splicing is complete). Which ones (provide

Explanation / Answer

12. Proximal promoter

13. 5' splice site, 3' splice site

14. Start codon, stop codon, cleavage and polyadenylation sequence, GU-rich sequence, poly A tail
