Final answer:
To determine the correct amino acid sequence, we use a genetic code chart to translate mRNA codons. Given an mRNA sequence, each triplet codon is translated into an amino acid, starting from the 5' end and ending at a stop codon. Methionine is often the start amino acid.
Step-by-step explanation:
The question revolves around the process of translating mRNA into an amino acid sequence, which is a fundamental concept in molecular biology, specifically in the area of gene expression and protein synthesis. To determine the correct sequence, one must use a genetic code chart to translate each codon into its corresponding amino acid. For example, given the mRNA sequence 5'-AUGCUGAAUUGCGUAGGA-3', the corresponding amino acids would be methionine (AUG), leucine (CUG), asparagine (AAU), alanine (UGCG), and the sequence would terminate at the stop codon (UAG), resulting in the sequence Met-Leu-Asn-Ala. The sequences are read from the 5' to the 3' end and protein synthesis starts with the N-terminal amino acid, which in this case is methionine, typically the initiation amino acid for protein synthesis, although it is often removed in further processing steps.
