Question

print out the genetic code in the list of materials to answer this question.
which amino acids are in the code auggucggu?
arginine, histidine, and cysteine
methionine, glutamine, and alanine
methionine, valine, and glycine
methionine, valine, and aspartic acid

Explanation:

To determine the amino acids from the genetic code \( \text{AUGGUCGGU} \), we divide the sequence into codons (groups of 3 nucleotides): \( \text{AUG} \), \( \text{GUC} \), \( \text{GGU} \).

• \( \text{AUG} \) codes for methionine (start codon).
• \( \text{GUC} \) codes for valine.
• \( \text{GGU} \) codes for glycine.

We check the options:

• First option: Amino acids don’t match.
• Second option: Glutamine (from \( \text{CAG/Q} \), \( \text{CAA/Q} \)) and alanine (from \( \text{GCX} \)) don’t match.
• Third option: Methionine (\( \text{AUG} \)), valine (\( \text{GUC} \)), glycine (\( \text{GGU} \)) match.
• Fourth option: Aspartic acid (from \( \text{GAU/D} \), \( \text{GAC/D} \)) doesn’t match.

Answer:

C. methionine, valine, and glycine
