**Transcription for Educational Website**The sequence of a polypeptide is determined by the order of codons that specify the amino acids in the polypeptide. How many different sequences of codons can specify the polypeptide sequence methionine-histidine-lysine? (Use the table to find the number of possibilities.)**Codon Table Explanation:**The table provided maps each set of three nucleotides (codons) to their corresponding amino acids. It is arranged by the first, second, and third bases of the codon.- **First Base (Left Column):** U, C, A, G- **Second Base (Top Row):** U, C, A, G- **Third Base (Right Column):** U, C, A, G**Codons for the Specific Amino Acids:**- **Methionine (Met):** AUG- **Histidine (His):** CAU, CAC- **Lysine (Lys):** AAA, AAGTo determine the number of different sequences of codons for the methionine-histidine-lysine sequence, consider the following:- There is only one codon for Methionine: AUG- There are two codons for Histidine: CAU or CAC- There are two codons for Lysine: AAA or AAGUsing combinations, calculate the number of possibilities:\[ 1 \times 2 \times 2 = 4 \]Thus, there are **4 different sequences** that can specify the polypeptide sequence methionine-histidine-lysine.**Answer Choices:**- ○ 8- ○ 1- ○ 2- ● 4

Proteins are the ultimate products of the genes. DNA is transcribed into m RNA and this is translated into the protein. During translation m RNA is processed in the ribosome where the triplet codons are added to each other. Each triplet codon represents an amino acid and forms an amino acid chains. This chain undergoes structural modification and finally forms proteins. Metheionine is coded by AUG Histidine is by – CAU, CAC Lysine is by- AAA, AAG So the possible sequences would be AUG-CAU-AAA AUG-CAC-AAG AUG-CAU-AAG AUG-CAC-AAA So, the answer is 4
