You are to determine the original DNA code for part of a hemoglobin protein molecule, especially for the 3 amino acid chain of threonine-proline-glutamate.
Procedure:
a) Write out the codon for each amino acid as used in the text and previous question. Label this set of 3 codons as mRNA.
b) Above this mRNA, write out the corresponding DNA. This is the "sense strand".
C) Above the sense strand write out the corresponding "antisense strand".
Label and record the three lines of letters.


13. Now, BELOW the mRNA triplet codons, construct the three tRNA anticodons and record it here.


15. A) when the tRNA anticodons match mRNA triplet codons, then the amino acid sequence synthesized is?

16. If a mistake is made, even in one nucleotide, what would you predict would occur in hemoglobin synthesis?

17. What actually determines which amino acids are linked in a functional hemoglobin molecule?

18. What is the mRNA sequence listed for threonine-proline-glutamate?

Please help! I have most of them finished just need to verify them :)

The sequence you wrote is the sequence of the mRNA. That is the sense strand. Just remember that sequences are written 5' ACU - CCC - GAA 3'

The DNA sequence? ... replace U with T
So ... 5' ACT CCC GAA 3'

The complementary sequence is the anti-sense strand
5' ACT CCC GAA 3'
3' TGA GGG CTT 5'

Remembering to write it 5'->3' the answer is 5' TTC GGG AGT 3'
