Final answer:
Using a genetic code chart to translate the given mRNA sequence CUAUGUGCUGUAACAGCCGAUGACCCG, the correct amino acid sequence is Leu - Cys - Pro - Phe, which corresponds to option (a).
Step-by-step explanation:
To determine the amino acid sequence corresponding to an mRNA strand, we use a genetic code reference that matches each three-nucleotide codon to its corresponding amino acid. Let's apply this process to the provided mRNA sequence:
- CUA corresponds to Leu (Leucine)
- UGC corresponds to Cys (Cysteine)
- UGC corresponds to Pro (Proline)
- UGU corresponds to Phe (Phenylalanine)
Based on the codon chart provided and reading the sequence from the 5' end, the mRNA strand CUAUGUGCUGUAACAGCCGAUGACCCG translates to the amino acid sequence Leu - Cys - Pro - Phe.
