from that sequence of tRNA anticodons, what is the sequence of amino acids that would be synthesized?

first, you have to go and get the complementary basepair seq for the tRNA anticodon, then use that and refer to a genetic code which is easily available on the web.

Adenine pairs with Uracil, Guanine with Cytosine.  So you have to find the pairs of each nitrogenous base on the tRNA codon, and then use those to figure out the amino acids.  There should be a chart of them on the internet.  There are 3 bases per amino acid.  The translation can't start unless there is first an AUG (start) codon.

Both of the answers are correct, but this is a bit of a trick question.  Keep in mind that RNA (and DNA) sequences are typically written in the 5'->3' direction.  So, if you have the mRNA sequence 5'-AUG-3', the anticodon for the tRNA would be 5'-CAU-3'.  This would allow the tRNA to basepair with the mRNA in an antiparallel fashion:

3'-UAC-5' tRNA
5'-AUG-3' mRNA

So, be careful here. The easiest way to do this is to write out the mRNA sequence, and then write the tRNA sequence as I did above.  Then read the tRNA sequence in the 5'->3' direction and you'll have the anticodon.
