Question

This is a short segment of a region of DNA coding for a protein. Not shown are the upstream and downstream regions. Use the codon dictionary in your textbook to complete the following table. Assume that reading is from left to right and that the columns represent transcriptional and translational alignment. Numbers across the top represent position. Numbers on the left represent the following: 1=DNA strand 1, 2=DNA strand 2, 3=mRNA transcribed, 4=amino acids in protein.

5. [2pt]
What is the nucleotide sequence of the first DNA strand (row 1)? Enter your answer from 5' to 3' but omit the 5' and 3' indications (e.g. CTTATATCG...)

Answer:  
6. [2pt]
What is the nucleotide sequence of the second DNA strand (row 2)? Enter your answer from 5' to 3' but omit the 5' and 3' indications (e.g. CTTATATCG...)

Answer:  
7. [2pt]
What is the nucleotide sequence of the transcribed mRNA (row 3)? Enter your answer from 5' to 3' but omit the 5' and 3' indications (e.g. CTTATATCG...)

Answer:  
8. [2pt]
What is the amino acid sequence of the protein produced (row 4)? Enter your answer from amino to carboxy terminus but omit the N and C indications (e.g. TyrTrpGlu...)
