If this is a true genomic sequence, you can only start at a start codon, which is ATG.
But, this appears to be a template sequence, so we'll do transcription now:
The corresponding mRNA is:
AUG AAU GGC UCU AAG AAG AAA UAG
AUG is a valid start codon. And by the way, that's methionine (Met or M).
Now the rest:
AAU=Asparagine (Asn or N)
GGC=Glycine (Gly or G)
UCU=Serine (Ser or S)
AAG=Lysine (Lys or K)
AAG=Lysine again (Lys or K)
AAA=Lysine again (Lys or K)
UAG=Stop codon
So the end sequence is Met-Asn-Gly-Ser-Lys-Lys-Lys, or in single-letters, MNGSKKK.

In order for you to answer this question, your teacher should have given you either a printout of amino acid nucleotide sequences, or referred you to the corresponding page in the textbook.
Once you get your hands on that, it's a simple task of matching up each triplet (3 codons) to an amino acid, and listing them in order.
As for the mRNA sequence, keep in mind that RNA has uracil instead of thymine.
Hope this clarifies it for you!
