GREYUIT [131]

Answer:

In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).

Explanation:

Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.

From the sequence:

AUGGUGCAUGUC

Four codons are obtained, each of which encodes a different amino acid:

<em>Codons:          AUG-GUG-CAU-GUC</em>

<em>Amino acids:  Met - Val - His - Val</em>

<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>
