I'll start from the very beginning.
This is the DNA strand that you gave me:
AAA TAC CCC GTA ATG GCA TAG GTC TGC ACT
In order to turn this into mRNA, you have to add complimentary bases. Remember that RNA does not have thymine! so replace thymine with uracil instead.
Pairings: A-U and G-C
DNA: AAA TAC CCC GTA ATG GCA TAG GTC TGC ACT
RNA: UUU AUG GGG CAU UAC CGU AUC CAG AGC UGA
Important to note: ribosomes start reading from the start codon (AUG) and stops once it encounters a stop codon (UAA or UGA or UAG).
You then have to use the codon chart to find your amino acids sequence.
RNA: UUU AUG GGG CAU UAC CGU AUC CAG AGC UGA
phe start gly his tyr arg iso glu ser stop

Now using the RNA sequence that you gave me:
RNA: AAA GTC GCT CTG AGT TGT TAT
lys val ala leu ser cys tyr
*I will convert all T's to U's
Sorry it took so long...
