Answer:
A. AAU GAU ACU GCA GC would be the mRNA sequence.
B. Asparagine, Aspartic acid, Threonine, Alanine, (I couldn't get the last one.)
C. AAU GUA CUG CAG C
Explanation:
A. You need to switch A to U, C to G, G to C, and T to A
B. I used the full names of the amino acids. I didn't use the abbreviations on the codon chart.
C. After the 5th nitrogen base, you need to move the rest of the bases into the "3 letter groups."
P.S. you gave "CG" at the end of the original sequence. I couldn't completely answer for that codon. If you weren't given that last base, that is OK.
