Question

question 22 of 25
which amino acid chain will be formed by the codons shown below?
aag aga ugu

a. lys-ser-cys
b. asn-ser-cys
c. asn-arg-cys

Explanation:

Step1: Identify the amino acid for AAG

Looking at the codon table, for the codon \(AAG\), the first base is \(A\), the second base is \(A\), and the third base is \(G\). In the row where the first base is \(A\), and the column where the second base is \(A\), we find that \(AAG\) codes for Lys (Lysine).

Step2: Identify the amino acid for AGA

For the codon \(AGA\), the first base is \(A\), the second base is \(G\). In the row with first base \(A\) and column with second base \(G\), we see that \(AGA\) codes for Ser (Serine).

Step3: Identify the amino acid for UGU

For the codon \(UGU\), the first base is \(U\), the second base is \(G\). In the row with first base \(U\) and column with second base \(G\), we find that \(UGU\) codes for Cys (Cysteine).

So the amino - acid chain is Lys - Ser - Cys.

Answer:

A. Lys - Ser - Cys
