So, the non-template strand is the top strand (you can tell because it reads 5' -> 3'). You get the amino acid sequence by looking at the three-nucleotide codons in the top strand; in this case, they would be ATG ATA CTA AGG CCC, right? The mRNA codons would be just the same except that the Ts wold all b replaced by Us, so it would go AUG AUA CUA AGG CCC, right? 5 codons should mean 5 amino acids (unless one is a stop codon, but that's not the case here), so (a) isn't correct.

You can use one of the codon tables below to figure out whether b, c or d is the correct answer. The first one uses the DNA codons, and the second one uses the RNA codons. Think of it as a puzzle or a game. Have fun!
