The sequence 5'-aug gug uca ggg uaa-3' is an mRNA sequence that can be translated into a protein using the genetic code. The codons translate as follows: AUG (start codon) codes for Methionine (Met), GUG codes for Valine (Val), UCA codes for Serine (Ser), GGG codes for Glycine (Gly), and UAA is a stop codon, signaling the end of translation. Therefore, this sequence encodes the peptide Met-Val-Ser-Gly.
