Answer: (D)

Verified step by step guidance

1. Identify the mRNA codon sequence provided: 5′–AUG–UCU–UCG–UUA–UCC–UUG–3′.
2. Use the codon chart to translate each codon into its corresponding amino acid. Start with the first codon 'AUG', which codes for Methionine (Met).
3. Translate the second codon 'UCU'. According to the chart, 'UCU' codes for Serine (Ser).
4. Translate the third codon 'UCG'. The chart shows that 'UCG' also codes for Serine (Ser).
5. Continue translating the remaining codons: 'UUA' codes for Leucine (Leu), 'UCC' codes for Serine (Ser), and 'UUG' codes for Leucine (Leu).
