Answer:
393 nitrogenous bases
Step-by-step explanation:
During the Translation process, the nitrogenous bases on the mRNA are read by the tRNA in triplets called codons. Each codon codes for a specific amino acid which gets bonded to each other via peptide bonds and forms a peptide.
In the given question since the protein contains 131 amino acids these might have been coded by 393 nitrogenous bases shown below:
Since 1 amino acid coded by 3 nitrogenous bases
so 131 amino acid will be coded by- 131 x 3 = 393 bases.
Thus, 393 bases are the correct answer.
