Final answer:
The given mRNA sequence does not start with ACU as specified, so there is no match between the given sequence and the specified start codon.
Step-by-step explanation:
The given mRNA sequence is TGACGGGTACTCGCTGGGGAAGCCCGAGCCCCTTACTTAGC. In order to find the amino acid sequence, we need to start with the start codon AUG.
However, the question specifies that the sequence should also start with ACU. The start codon AUG codes for methionine, but ACU codes for threonine. Therefore, there is no match between the given sequence and the specified start codon.
