Since the sequence starts with an initiation codon and ends with a stop codon I think it's safe to conclude that this is the coding strand.  The coding strand has the same sequence as the transcribed RNA (except T>U). This is because it is the other strand of the DNA that is the template for the synthesis of an RNA. The RNA is indeed made 5'>3', but the template it uses has to run in the opposite direction.

    5’-ATGTACTTCCATCTGGAATAG-3’
    3'-TACATGAAGGTAGACCTTATC-5' template strand


    5'-AUGUACUUCCAUCUGGAAUAG-3’ mRNA transcript
    3'-TACATGAAGGTAGACCTTATC-5' template strand (read from left to right by the polymerase)


and the sequence of the protein is MetTyr...etc
