GUA (Val GCA (Aie)

Explanation / Answer

Answere : The mRNA contain protein sequence in the form of codon. A codon is a sequence of three nucleotide which specify a particular amino acid. The protein sequence for above mRNA UAGUUUCGGGGCUAG is Met-Phe-Arg-Gly.

"AUG" act as start codon which codes for methionine.

"UAG" act as stop codon which do not code for any amino acid and leads to terminnation of polypeptide synthesis.
