Verified step by step guidance1
Identify the start codon in the mRNA sequence. The start codon is 'AUG', which signals the beginning of translation.
Divide the mRNA sequence into codons, which are groups of three nucleotides. Starting from the 'AUG', the sequence is divided as follows: AUG, AUC, GAU, CAC, UAA.
Recognize that 'UAA' is a stop codon, which signals the termination of translation. Therefore, the translation process stops at this codon.
Count the number of codons between the start codon 'AUG' and the stop codon 'UAA'. These codons represent the amino acids in the peptide.
Determine the number of amino acids by counting the codons: AUG, AUC, GAU. This results in a peptide that is 3 amino acids long.
