Ok so you're given the base sequence, and told how many times each amino acid is coded for. Met is coded for twice, so you need to find a three base sequence that appears twice. Similarly, Arg appears 3 times, so you need to find a three base sequence that appears three times. Asn will fit in somewhere where the sequence is different from the sequences for Met and Arg.
