Minchanka [31]

Answer:

The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).

Explanation:

Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.

  • <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine. </em>
  • <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete.  UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>

The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.
