Don't know what this if for, but if it is for a class and the teacher is trying to make it a trick question, you also need to look at the other reading frames (granted there is no start codon in the other reading frames, but you didn't stipulate that this sequence wasn't taken from the middle of a gene):

1st Open reading frame (ORF): AUG UUU GGG CCC AAA UAA CCG

2nd ORF: UGU UUG GGC CCA AAU AAC CCG

3rd ORF: GUU UGG GCC CAA AUA ACC

BTW, many proteins (especially viral proteins where they have to pack as much as possible into a small genome) are translated from overlapping reading frames. So that in some cases, one strand of RNA can produce three separate proteins.
