Codon wheel is used to do which of the following?

• A. Decode codons and determine the amino acid sequence
• B. Transcribe DNA into RNA
• C. Replicate DNA
• D. Transport amino acids to ribosomes

Answer: (A)

The main idea is translating RNA codons into the corresponding amino acids using the genetic code. A codon wheel visually maps every three-nucleotide mRNA codon to its amino acid (or a stop signal). By following the codons in an mRNA sequence around the wheel, you can read off the exact amino acid sequence that will be built during translation. This is why the codon wheel is used to decode codons and determine the amino acid sequence—it directly links codons to their protein-building instructions, including recognizing start and stop signals like AUG and the stop codons. It isn’t used for transcription (DNA to RNA), DNA replication, or transporting amino acids to the ribosome; those are governed by other cellular processes and molecules.
