During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amino acids are specified by the string of codons. What amino acid sequence does the following mRNA nucleotide sequence specify?

Question

During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amino acids are specified by the string of codons. What amino acid sequence does the following mRNA nucleotide sequence specify?

5′−AUGGCAAGAAAA−3′

Express the sequence of amino acids using the three-letter abbreviations, separated by hyphens (e.g., Met-Ser-Thr-Lys-Gly).

To determine the amino acid sequence specified by the mRNA nucleotide sequence 5′−AUGGCAAGAAAA−3′, we can first break the sequence into its respective codons (groups of three nucleotides) and then translate those codons into their corresponding amino acids.

The mRNA sequence 5′−AUGGCAAGAAAA−3′ can be divided into the following codons:

1. AUG
2. GCA
3. AGA
4. AAA

Next, we can use the standard genetic code to translate these codons:

1. **AUG** - Methionine (Met) - Start codon
2. **GCA** - Alanine (Ala)
3. **AGA** - Arginine (Arg)
4. **AAA** - Lysine (Lys)

Putting it all together, the corresponding amino acid sequence is:

**Met-Ala-Arg-Lys**

So the final answer is:

**Met-Ala-Arg-Lys**
