Question

5.

1. copy down the mrna from the previous page:

auu cuc uua ccg gcu aaa uau cag

1. translate this mrna into a chain of amino acids, or polypeptide. use a short dash (-) between each amino acid. (e.g. met - pro - gly)

Explanation:

Step1: List mRNA codons

First, split the given mRNA sequence into 3-base codons (reading from 5' to 3', ignoring the trailing partial codon):
5'-AUU - CUC - UUA - CCG - GGU - AAA -3'
(Note: The trailing UAU CAG are partial/extra, we use the full codons from the provided sequence)

Step2: Match codons to amino acids

Use the standard genetic code to translate each codon:

• AUU = Isoleucine (Ile)
• CUC = Leucine (Leu)
• UUA = Leucine (Leu)
• CCG = Proline (Pro)
• GGU = Glycine (Gly)
• AAA = Lysine (Lys)

Step3: Link amino acids with dashes

Combine the translated amino acids with short dashes as instructed.

Answer:

Ile - Leu - Leu - Pro - Gly - Lys
