Verified step by step guidance

Understand the role of codons in genetic coding: Codons are sequences of three nucleotides that correspond to specific amino acids or signal the start or stop of protein synthesis.

Identify the start codon: The start codon is responsible for signaling the beginning of translation, where the ribosome starts synthesizing the protein.

Recognize the universal start codon: In most organisms, the start codon is AUG, which codes for the amino acid methionine.

Differentiate between start and stop codons: Stop codons signal the end of protein synthesis. The common stop codons are UAA, UAG, and UGA.

Apply this knowledge to the given options: Among the options provided (AUG, UAA, UAG, UGA), identify which one is the start codon based on the information that AUG is universally recognized as the start codon.
