Aprotein contains 131 amino acids. how many bases will there
beon the mrna strand corresponding to these amino acids and how
doyou know?

393 nitrogenous bases

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.
