need help with this biology question.

Answer:
AUG CUA GCU
Explanation:
The anticodon is brought to the mRNA by the tRNA or the transfer RNA. Each anticodon codes for a specific amino acid attached to the tRNA. The base pairs for mRNA to tRNA are:
A = U
U = A
C = G
G = C
So in your case
mRNA sequence: UAC GAU CGA
tRNA sequence: AUG CUA GCU
